使用Spring的HBase連接失敗

Question

我有一個僅使用Java客戶端的HBase簡易應用程序，一切正常。 但是，當我嘗試使用spring制作相同的應用程序時，zookeeper拒絕了該連接或將其關閉，而我真的無法理解會發生什么。 這是一些代碼：xml config：

 <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:hdp="http://www.springframework.org/schema/hadoop"
   xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/hadoop 
    http://www.springframework.org/schema/hadoop/spring-hadoop.xsd">

    <hdp:configuration>
    </hdp:configuration> 
    <hdp:hbase-configuration delete-connection="true" />
    <bean id="hTemplate" class="org.springframework.data.hadoop.hbase.HbaseTemplate" >
        <property name="configuration" ref="hbaseConfiguration"></property>
    </bean>
    <bean id="usingHBase" class="com.mycompany.usinghbase.UsingHBase" />
 </beans>

這是我的簡單方法：

public class UsingHBase {

    @Autowired
    @Qualifier("hTemplate")
    private HbaseTemplate hBaseTemplate;

    public void addData(final String key, final String value) throws IOException {
        hBaseTemplate.execute("new_table", new TableCallback<Object>() {
            public Object doInTable(HTableInterface hti) throws Throwable {
              Put p = new Put(Bytes.toBytes("zz"));
              p.add(Bytes.toBytes("zz"), Bytes.toBytes(key), Bytes.toBytes(value));
                hti.put(p);
                return null;
            }
        });
    }

    public List<Object> findAll() {
        return hBaseTemplate.find("new_table", "zz", new RowMapper<Object>() {
            public Object mapRow(Result result, int rowNum) throws Exception {
                return result.toString();
            }
        });
    }

        public void DeleteData(final String key) throws IOException {
        hBaseTemplate.execute("new_table", new TableCallback<Object>() {
            public Object doInTable(HTableInterface hti) throws Throwable {
        Delete delete = new Delete(Bytes.toBytes("zz"));
        delete.deleteColumns(Bytes.toBytes("zz"), Bytes.toBytes(key));
        hti.delete(delete);
                return null;
            }
        });
    }
}

這是我的測試用例：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "file:src/main/java/spring.xml")
public class UsingHBaseTest {

    @Autowired
    @Qualifier("hTemplate")
    private HbaseTemplate hBaseTemplate;

    @Autowired
    @Qualifier("usingHBase")
    private UsingHBase usingHBase;

    @Before
    public void setUp() {
    }

    @Test
    public void testAddData() throws Exception {
        System.out.println("addData");
        long startTime = System.currentTimeMillis();
    for (int i=1; i <= 1000; i++) {
            String column = "k" + i;
            String value = "v" + i;
            usingHBase.addData(column, value);
    }
    long EndTime = System.currentTimeMillis();
    System.out.println("Put value: " + (EndTime - startTime));
    }

    @Test
    public void testFindAll() {
        System.out.println("findData");
        long startTime = System.currentTimeMillis();
        usingHBase.findAll();
    long EndTime = System.currentTimeMillis();
    System.out.println("Put value: " + (EndTime - startTime));
    } 

    @Test
    public void testDeleteData() throws IOException {
        System.out.println("deleteData");
        long startTime = System.currentTimeMillis();
    for (int i=1; i <= 1000; i++) {
            String column = "k" + i;
            usingHBase.DeleteData(column);
    }
    long EndTime = System.currentTimeMillis();
    System.out.println("delete value: " + (EndTime - startTime));
    }
}

堆棧跟蹤顯示了什么：

請幫助。 我很需要你！

Answer 1

您必須在xml中指定Zookeeper仲裁和端口

<hdp:configuration id="hadoopConfiguration">
    hbase.zookeeper.quorum=mynode
    hbase.zookeeper.property.clientPort=2181
</hdp:configuration> 
<hdp:hbase-configuration id="hbaseConfiguration" delete-connection="true" configuration="hadoopConfiguration" />

Answer 2

在啟動zookeeper，hbase regionservers和master之后，嘗試運行您的應用程序。 該代碼然后應該工作。
