hive鏈接hbase外部表錯誤，Can't get the locations

在hive中執行建立hbase的外部表，執行建立腳本：

hive> CREATE EXTERNAL TABLE hbase_userFace(id string, mobile string,name string) 
    > STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' 
    > WITH SERDEPROPERTIES("hbase.columns.mapping" = ":key,faces:mobile,faces:name")
    > TBLPROPERTIES("hbase.table.name" = "userFace");

報錯以下：

看錯誤應該是連不上hbase，hbase是用zookeeper管理的，進行以下測試：

1. 測試單節點hbase的鏈接

$ hive -hiveconf hbase.master=master:60000

進入hive的cli後，執行建立外部表的腳本，發現仍是報錯。

2. 測試集羣hbase的鏈接

hive -hiveconf hbase.zookeeper.quorum=slave1,slave2,master,slave4,slave5,slave6,slave7

進入hive的cli後，執行建立外部表的腳本，發現建立成功。

因而可知，是hive讀取hbase的zookeeper時出錯了。查看hive-site.xml文件中，有個名爲hive.zookeeper.quorum的property，複製一份改成hbase.zookeeper.quorum的屬性。以下：

  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>slave1,slave2,master,slave4,slave5,slave6,slave7</value>
    <description>
    </description>
  </property>

至此，問題解決，建立hbase外部表成功。
