  • hadoop系列 第二坑: hive hbase关联表问题

    关键词:

    hive创建表卡住了

    创建hive和hbase关联表卡住了

    其实针对这一问题在info级别的日志下是看出哪里有问题的(为什么只能在debug下才能看见呢,不太理解开发者的想法)。

    以调试模式进入hive客户端:

    hive --hiveconf hive.root.logger=DEBUG,console
    

    执行创建关联表的语句

    create table IF NOT EXISTS event_content_temp
    (id string,pack string,activity string,title string, sx string, dx string, num bigint) 
    stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' 
    with serdeproperties ("hbase.columns.mapping" = ":key,cf:pack,cf:activity,cf:title,cf:sx,cf:dx,cf:num") 
    tblproperties ("hbase.table.name" = "event_content_temp");

    显示错误日志:

    很显然是zookeeper的问题,可是在ClouderaManager中已经设置了呀,核对之后发现只有Hive Service Configuration Safety Valve for hive-site.xml里加了属性

    <property>
      <name>hive.aux.jars.path</name>  
      <value>
             file:///opt/cloudera/parcels/CDH-4.7.1-1.cdh4.7.1.p0.47/lib/hive/lib/hive-hbase-handler-0.10.0-cdh4.7.1.jar,
             file:///opt/cloudera/parcels/CDH-4.7.1-1.cdh4.7.1.p0.47/lib/hive/lib/hbase.jar,
             file:///opt/cloudera/parcels/CDH-4.7.1-1.cdh4.7.1.p0.47/lib/hive/lib/zookeeper.jar
      </value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>ip-xxx.cn-north-1.compute.internal:2181,ip-xxxx.cn-north-1.compute.internal:2181,ip-xxxx-112.cn-north-1.compute.internal:2181,ip-xxxx-108.cn-north-1.compute.internal:2181,ip-xxxx111.cn-north-1.compute.internal:2181</value>
    </property>

    Hive Client Configuration Safety Valve for hive-site.xml里没有添加,这里很好理解,hive服务里配置了hbase的zk,但是hive客户端没有配置(hive-site.xml),建议二者配置一致!

    配置完之后,对于关联表的操作都可以顺利完成。

    总结:建议hive服务端和客户端的hive-site.xml一样

    另外,我建了个QQ群:305994766,希望对大数据、算法研发、系统架构感兴趣的朋友能够加入进来,大家一起学习,共同进步(进群请说明自己的公司-职业-昵称)
