Hive - 外部表创建失败解决方案

在hdp平台上，使用hive控制台创建一个hbase的外部表，出现ERROR : FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:org.apache.hadoop.hbase.TableNotFoundException，原因是启动了Ranger认证，hive用户需要有hbase的创建权限才可以。

为hive用户添加权限

Hbase创建表语句如下

create 'test','ext'
put 'test','r1','ext:userId','abc'

hive创建外部表

create external table abc(rowkey string,userId string) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES("hbase.columns.mapping" = ":key,ext:userId") TBLPROPERTIES("hbase.table.name" = "test");

显示成功结果如下
