hadoop系列 第二坑： hive hbase关联表问题

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-.compute.internal:,ip-xxxx.cn-north-.compute.internal:,ip-xxxx-.cn-north-.compute.internal:,ip-xxxx-.cn-north-.compute.internal:,ip-xxxx.cn-north-.compute.internal:</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
