Konfiguration hinzufügen
Der offizielle Weg führt über XML, das einfach wie folgt umgeschrieben wird:
@Configuration
public class HBaseConfiguration {
@Value("${hbase.zookeeper.quorum}")
private String zookeeperQuorum;
@Value("${hbase.zookeeper.property.clientPort}")
private String clientPort;
@Value("${zookeeper.znode.parent}")
private String znodeParent;
@Bean
public HbaseTemplate hbaseTemplate() {
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
conf.set("hbase.zookeeper.quorum", zookeeperQuorum);
conf.set("hbase.zookeeper.property.clientPort", clientPort);
conf.set("zookeeper.znode.parent", znodeParent);
return new HbaseTemplate(conf);
}
}application.yml:
hbase: zookeeper: quorum: hadoop001,hadoop002,hadoop003 property: clientPort: 2181 zookeeper: znode: parent: /hbase
HbaseTemplate test:
@Service
@Slf4j
public class HBaseService {
@Autowired
private HbaseTemplate hbaseTemplate;
public List<Result> getRowKeyAndColumn(String tableName, String startRowkey, String stopRowkey, String column, String qualifier) {
FilterList filterList = new FilterList(FilterList.Operator.MUST_PASS_ALL);
if (StringUtils.isNotBlank(column)) {
log.debug("{}", column);
filterList.addFilter(new FamilyFilter(CompareFilter.CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(column))));
}
if (StringUtils.isNotBlank(qualifier)) {
log.debug("{}", qualifier);
filterList.addFilter(new QualifierFilter(CompareFilter.CompareOp.EQUAL, new BinaryComparator(Bytes.toBytes(qualifier))));
}
Scan scan = new Scan();
if (filterList.getFilters().size() > 0) {
scan.setFilter(filterList);
}
scan.setStartRow(Bytes.toBytes(startRowkey));
scan.setStopRow(Bytes.toBytes(stopRowkey));
return hbaseTemplate.find(tableName, scan, (rowMapper, rowNum) -> rowMapper);
}
public List<Result> getListRowkeyData(String tableName, List<String> rowKeys, String familyColumn, String column) {
return rowKeys.stream().map(rk -> {
if (StringUtils.isNotBlank(familyColumn)) {
if (StringUtils.isNotBlank(column)) {
return hbaseTemplate.get(tableName, rk, familyColumn, column, (rowMapper, rowNum) -> rowMapper);
} else {
return hbaseTemplate.get(tableName, rk, familyColumn, (rowMapper, rowNum) -> rowMapper);
}
}
return hbaseTemplate.get(tableName, rk, (rowMapper, rowNum) -> rowMapper);
}).collect(Collectors.toList());
}
