      Description

      If you create a table on top of hbase in hive and issue a "show create table <hbase_table>", it gives a bad DDL. It should not show LOCATION:

      [hive]$ cat /tmp/test_create.sql
      CREATE EXTERNAL TABLE nba_twitter.hbase2(
      key string COMMENT 'from deserializer',
      name string COMMENT 'from deserializer',
      pdt string COMMENT 'from deserializer',
      service string COMMENT 'from deserializer',
      term string COMMENT 'from deserializer',
      update1 string COMMENT 'from deserializer')
      ROW FORMAT SERDE
      'org.apache.hadoop.hive.hbase.HBaseSerDe'
      STORED BY
      'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
      WITH SERDEPROPERTIES (
      'serialization.format'='1',
      'hbase.columns.mapping'=':key,srv:name,srv:pdt,srv:service,srv:term,srv:update')
      LOCATION
      'hdfs://nameservice1/user/hive/warehouse/nba_twitter.db/hbase'
      TBLPROPERTIES (
      'hbase.table.name'='NBATwitter',
      'transient_lastDdlTime'='1386172188')
      Trying to create a table using the above fails:

      [hive]$ hive -f /tmp/test_create.sql
      cli "-f /tmp/test_create.sql"
      Logging initialized using configuration in jar:file:/opt/cloudera/parcels/CDH-4.4.0-1.cdh4.4.0.p0.39/lib/hive/lib/hive-common-0.10.0-cdh4.4.0.jar!/hive-log4j.properties
      FAILED: Error in metadata: MetaException(message:LOCATION may not be specified for HBase.)
      FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

      However, if I remove the LOCATION, then the DDL is valid.
