Hadoop学习全程记录——使用Sqoop将MySQL中数据导入到Hive中http://www.linuxidc.com/Linux/2012-01/51993.htm
获取sqoop:http://sqoop.apache.org/
Step1. 下载sqoop及mysqlconnector并解压
Step2. 将解压后的connector中的jar包拷贝到sqoop的lib目录下
修改bin目录下 configure-sqoop 文件:
注释掉hbase和 zookeeper检查,因为目前还没有启用hbase/zookeeper等hadoop上的组件
Step3. 设置环境变量
注意重新连接使环境变量生效!
Sqoop:
Hadoop_home:
测试运行下sqoop:
可以使用help命令查看帮助:
Step4. 测试mysql导入HDFS:
创建一张测试表并插入数据:
利用sqoop将测试表导入到hdfs:
注意:可以用sqoop help import 查看帮助信息
登陆mysql创建用户,授予从任何ip登陆mysql权限
这里创建用户sqoopuser
GRANT ALL PRIVILEGES ON *.* TO 'sqoopuser'@'%' IDENTIFIED BY 'sqoopuser' WITH GRANT OPTION;
查看数据库列表:
sqoop list-databases --connect jdbc:mysql://10.55.15.89:3306/ --username sqoopuser --P
执行导入命令将sqoop_test表导入到hdfs:
sqoop import --connect jdbc:mysql://10.55.15.89:3306/sqoop_db --username sqoopuser --P --table sqoop_test -m 1

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
