hadoop2.4.0 ha 搭建-mysql教程-PHP中文網

问题导读：
1、hadoop ha是通过什么配置实现自动切换的？
2、配置中mapred与mapreduce的区别是什么？
3、hadoop ha两个namenode之间的关系是什么？

-- Step 4. 创建相关目录

mkdir ~/logs
mkdir ~/mydata

-- 备注：mydate目录下的相关子目录会自动生成，不需要创建。
-- 在每台集群机器上创建如上两个目录，并同步 $HADOOP_HOME/etc/hadoop目录下的所有文件到各节点

-- Step 5. 启动Zookeeper、JournalNode、格式化Hadoop集群并启动

-- Step 5.1 启动Zooker (ZK集群是funshion-hadoop194、funshion-hadoop195、funshion-hadoop196、funshion-hadoop197、funshion-hadoop198 五台服务器)

[hadoop@funshion-hadoop194 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop195 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop196 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop197 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop198 bin]$ /usr/local/zookeeper/bin/zkServer.sh start

-- 可以如下查看Zookeeper集群各节点的状态：
/usr/local/zookeeper/bin/zkServer.sh status

-- 然后在某一个namenode节点执行如下命令，创建命名空间
[hadoop@funshion-hadoop194 bin]$ cd $HADOOP_HOME
[hadoop@funshion-hadoop194 hadoop]$ ./bin/hdfs zkfc -formatZK

-- 备注：停止zookeeper相关命令类似如下：
/usr/local/zookeeper/bin/zkServer.sh stop
/usr/local/zookeeper/bin/zkServer.sh restart

-- Step 5.2 启动JournalNode进程(在funshion-hadoop194、funshion-hadoop195、funshion-hadoop196、funshion-hadoop197、funshion-hadoop198五台服务器上分别执行)：

[hadoop@funshion-hadoop194 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop196 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop197 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop198 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode

-- Step 5.3 格式化Hadoop集群并启动：

-- 在 funshion-hadoop194 上执行：
[hadoop@funshion-hadoop194 bin]$ $HADOOP_HOME/bin/hdfs namenode -format mycluster
[hadoop@funshion-hadoop194 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start namenode

-- 上步执行完后，在 funshion-hadoop195 上执行：
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs namenode -bootstrapStandby
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start namenode

-- 上步执行完后，可以继续在某个 namenode 执行 $HADOOP_HOME/sbin/start-all.sh 启动datanode及yarn相关进程。

-- 因为是配置的自动故障转移，所以不能手工切换namenode的active和stadby角色。

-- 可以通过haadmin查看每个Service的角色状态：
[hadoop@funshion-hadoop194 lab]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn1
standby
[hadoop@funshion-hadoop194 lab]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn2
active
[hadoop@funshion-hadoop194 lab]$

-- 通过hdfs-site.xml中的如下配置，我们知道nn1是在 funshion-hadoop194上的namenode服务，nn2是funshion-hadoop195上的namenode服务

dfs.namenode.rpc-address.mycluster.nn1
funshion-hadoop194:8020

dfs.namenode.rpc-address.mycluster.nn2
funshion-hadoop195:8020

-- 所以，我们可以尝试 kill 掉 nn2(状态为active的namenode进程，然后去查看nn1的角色是否改变：
[hadoop@funshion-hadoop195 bin]$ jps
3199 JournalNode
3001 NameNode
1161 QuorumPeerMain
3364 DFSZKFailoverController
4367 Jps

[hadoop@funshion-hadoop195 bin]$ kill -9 3001
[hadoop@funshion-hadoop195 bin]$ jps
3199 JournalNode
1161 QuorumPeerMain
3364 DFSZKFailoverController
4381 Jps

[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn1
active
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start namenode
starting namenode, logging to /usr/local/hadoop/logs/hadoop-hadoop-namenode-funshion-hadoop195.out
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn1
active
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn2
standby

-- 甚至可以直接reboot状态为active的namenode节点(执行操作系统的重启动作，看另一个standby状态的namenode节点是否能正常转换成acitve状态
-- 甚至可以在有作业运行的时候去执行reboot操作系统(namenode的active节点执行)以测试双节点故障转移是否确实健壮

[hadoop@funshion-hadoop194 ~]$ nohup sh /home/hadoop/datateam/ghh/lab/log_catch_hour_lzo.sh 'http://192.168.116.61:8081/website/pv/2' 'hdfs://mycluster/dw/logs/web/origin/pv/2' 20140524 20140525 0 23 &

-- nohup sh /home/hadoop/datateam/ghh/lab/log_catch_hour_lzo.sh 'http://192.168.116.61:8081/website/pv/2' 'hdfs://mycluster/dw/logs/web/origin/pv/2' 20140525 20140525 3 23 &

-- 上面这些脚本都是取公司的Oxeye的日志数据。（大家可以忽略此步操作）

-- Step 7. Hive安装(安装到196机器) (使用Hive与HBase整合安装；使用源码编译安装)

-- (其实应该先安装hbase，再安装hive可能顺序合理一点)

-- 参考：https://cwiki.apache.org/conflue ... iorto0.13onHadoop23

http://blog.csdn.net/hguisu/article/details/7282050
http://www.micmiu.com/bigdata/hive/hive-hbase-integration/

-- 源码下载编译操作如下：
mkdir -p /opt/software/hive_src
cd /opt/software/hive_src/
svn checkout http://svn.apache.org/repos/asf/hive/trunk/ hive_trunk
cd /opt/software/hive_src/hive_trunk

-- 下载以后，我们检查 hive_trunk目录下的pom.xml文件，发现hadoop-23.version这个变量已经引用了hadoop 2.4.0版本，所以，我们可以什么也不用修改，直接用ant去编译：

2.4.0

-- 或者如果发现版本不正确的话，我们可以这样指定参数执行(也可以修改pom.xml文件中对应正确的hadoop、hbase、zookeeper版本）：
-- 最后我选用的版本相关参数如下：

2.4.0

0.98.3-hadoop1
0.98.3-hadoop2
3.4.6

-- 最后，开始编译：
cd /opt/software/hive_src/hive_trunk
mvn clean package -DskipTests -Phadoop-2,dist

-- 最后，/opt/software/hive_src/hive_trunk/packaging/target　目录下的 apache-hive-0.14.0-SNAPSHOT-bin.tar.gz 文件，就是我们需要的安装包（这个版本还没有正式发布）

-- Step 7.1 My SQL安装(安装到194机器)，并在My SQL中创建名为hive的数据库用以存放hive元数据：

-- 安装如下rpm包
rpm -ivh MySQL-client-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-devel-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-embedded-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -e --nodeps mysql-libs-5.1.66-2.el6_3.x86_64
rpm -ivh MySQL-server-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-shared-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-shared-compat-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-test-5.6.17-1.linux_glibc2.5.x86_64.rpm

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.

You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.

Also, the account for the anonymous user has been removed.

In addition, you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test database.
This is strongly recommended for production servers.

See the manual for more instructions.

-- 查看安装生成的root用户随机密码：
[root@funshion-hadoop194 ~]# more /root/.mysql_secret
# The random password set for the root user at Mon Jun 9 18:18:48 2014 (local time): QVkyOjwSlAEiPaeT

-- 登录My SQL数据库并修改root密码，并创建名为hive的数据库与用户：
[root@funshion-hadoop194 ~]# service mysql start
Starting MySQL... SUCCESS!

-- 设置mysql服务自启动
chkconfig mysql on

[root@funshion-hadoop194 ~]# mysql -uroot -pQVkyOjwSlAEiPaeT

-- Step 7.2 解决hive安装包到/usr/local下，添加hive相关环境变量：

[root@funshion-hadoop194 ~]# cd /opt/software
[root@funshion-hadoop194 software]# ls -l|grep hive
-rw-r--r--. 1 root root 65662469 May 15 14:04 hive-0.12.0-bin.tar.gz
[root@funshion-hadoop194 software]# tar -xvf ./hive-0.12.0-bin.tar.gz
[root@funshion-hadoop194 software]# mv hive-0.12.0-bin /usr/local
[root@funshion-hadoop194 software]# cd /usr/local
[root@funshion-hadoop194 local]# chown -R hadoop.hadoop ./hive-0.12.0-bin
[root@funshion-hadoop194 local]# ln -s hive-0.12.0-bin hive

[hadoop@funshion-hadoop194 local]$ vi ~/.bash_profile
export HIVE_HOME=/usr/local/hive
export PATH=$PATH:$HIVE_HOME/bin

[hadoop@funshion-hadoop194 local]$ source ~/.bash_profile

-- Step 7.3 在My SQL数据库的hive数据库中执行创建hive元数据脚本：

-- Step 7.4 修改hive相关配置文件：

[hadoop@funshion-hadoop194 mysql]$ cd $HIVE_HOME/conf
[hadoop@funshion-hadoop194 conf]$ ls -l
total 92
-rw-rw-r--. 1 hadoop hadoop 81186 Oct 10 2013 hive-default.xml.template
-rw-rw-r--. 1 hadoop hadoop 2378 Oct 10 2013 hive-env.sh.template
-rw-rw-r--. 1 hadoop hadoop 2465 Oct 10 2013 hive-exec-log4j.properties.template
-rw-rw-r--. 1 hadoop hadoop 2870 Oct 10 2013 hive-log4j.properties.template

[hadoop@funshion-hadoop194 conf]$ mv hive-env.sh.template hive-env.sh
[hadoop@funshion-hadoop194 conf]$ mv hive-default.xml.template hive-site.xml

-- 7.4.1 修改 $HIVE_HOME/bin/hive-config.sh 文件，添加如下环境变量：

[hadoop@funshion-hadoop194 conf]$ vi $HIVE_HOME/bin/hive-config.sh

export JAVA_HOME=/usr/java/latest
export HIVE_HOME=/usr/local/hive
export HADOOP_HOME=/usr/local/hadoop

-- 7.4.2 修改 $HIVE_HOME/conf/hive-site.xml 的第2002行：

4.4.报错—请修改hive-site.xml:（vi编辑下： /auth）

-- 原值：
auth

-- 修改为：
auth）

-- 7.4.3 修改 $HIVE_HOME/conf/hive-site.xml 的如下property:

-- 7.4.3.1
-- 原值：

javax.jdo.option.ConnectionURL
jdbc:derby:;databaseName=metastore_db;create=true
JDBC connect string for a JDBC metastore

-- 修改为：

javax.jdo.option.ConnectionURL
jdbc:mysql://funshion-hadoop194:3306/hive?createDatabaseIfNotExist=true
JDBC connect string for a JDBC metastore

-- 7.4.3.2
-- 原值：

javax.jdo.option.ConnectionDriverName
org.apache.derby.jdbc.EmbeddedDriver
Driver class name for a JDBC metastore

-- 修改为：

javax.jdo.option.ConnectionDriverName
com.mysql.jdbc.Driver
Driver class name for a JDBC metastore

-- 7.4.3.3
-- 原值：

javax.jdo.option.ConnectionUserName
APP
username to use against metastore database

-- 修改为：

javax.jdo.option.ConnectionUserName
hive
username to use against metastore database

-- 7.4.3.4
-- 原值：

javax.jdo.option.ConnectionPassword
mine
password to use against metastore database

-- 修改为

javax.jdo.option.ConnectionPassword
bee56915
password to use against metastore database

-- 7.4.3.5
-- 原值：

hive.metastore.warehouse.dir
/user/hive/warehouse
location of default database for the warehouse

-- 修改为：

hive.metastore.warehouse.dir
hdfs://mycluster:8020/user/hive/warehouse
location of default database for the warehouse

-- 7.4.3.6
-- 原值：

hive.exec.scratchdir
/tmp/hive-${user.name}
Scratch space for Hive jobs

-- 修改为：

hive.exec.scratchdir
hdfs://mycluster:8020/tmp/hive-${user.name}
Scratch space for Hive jobs

-- 添加：

hbase.zookeeper.quorum
funshion-hadoop194,funshion-hadoop195,funshion-hadoop196,funshion-hadoop197,funshion-hadoop198

hive.aux.jars.path

file:///usr/local/hive/lib/hive-ant-0.14.0-SNAPSHOT.jar,
file:///usr/local/hive/lib/protobuf-java-2.5.0.jar,
file:///usr/local/hbase/lib/hbase-server-0.98.3-hadoop2.jar,
file:///usr/local/hbase/lib/hbase-client-0.98.3-hadoop2.jar,
file:///usr/local/hbase/lib/hbase-common-0.98.3-hadoop2.jar,
file:///usr/local/hbase/lib/hbase-common-0.98.3-hadoop2-tests.jar,
file:///usr/local/hbase/lib/hbase-protocol-0.98.3-hadoop2.jar,
file:///usr/local/hbase/lib/htrace-core-2.04.jar,
file:///usr/local/hive/lib/zookeeper-3.4.6.jar,
file:///usr/local/hive/lib/guava-11.0.2.jar

-- 上面格式是方便查看，真正使用下面的格式：将所有的jar包放到一行：

hive.aux.jars.path
file:///usr/local/hive/lib/hive-ant-0.14.0-SNAPSHOT.jar,file:///usr/local/hbase/lib/hbase-server-0.98.3-hadoop2.jar,file:///usr/local/hbase/lib/hbase-client-0.98.3-hadoop2.jar,file:///usr/local/hbase/lib/hbase-common-0.98.3-hadoop2.jar,file:///usr/local/hbase/lib/hbase-common-0.98.3-hadoop2-tests.jar,file:///usr/local/hbase/lib/hbase-protocol-0.98.3-hadoop2.jar,file:///usr/local/hbase/lib/htrace-core-2.04.jar,file:///usr/local/hive/lib/zookeeper-3.4.6.jar

-- 首先需要把hive/lib下的hbase包替换成安装的hbase的，需要如下几下：
hbase-client-0.98.2-hadoop2.jar
hbase-common-0.98.2-hadoop2.jar
hbase-common-0.98.2-hadoop2-tests.jar
hbase-protocol-0.98.2-hadoop2.jar
htrace-core-2.04.jar
hbase-server-0.98.2-hadoop2.jar

将hadoop节点添加到hive-site.xml中

hbase.zookeeper.quorum
所有节点

-- 另外，你必须在创建Hive库表前，在HDFS上创建/tmp和/user/hive/warehouse（也称为hive.metastore.warehouse.dir所指定的目录），并且将它们的权限设置为chmod g+w。完成这个操作的命令如下：
$ $HADOOP_HOME/bin/hadoop fs -mkdir /tmp
$ $HADOOP_HOME/bin/hadoop fs -mkdir /user/hive/warehouse
$ $HADOOP_HOME/bin/hadoop fs -chmod g+w /tmp
$ $HADOOP_HOME/bin/hadoop fs -chmod g+w /user/hive/warehouse

-- Step 7.5 启动并登录hive，并创建hive表

14/06/16 18:58:50 WARN conf.HiveConf: DEPRECATED: hive.metastore.ds.retry.* no longer has any effect. Use hive.hmshandler.retry.* instead
