Szehon Ho commented on HIVE-6853:
---------------------------------
Thanks , for the most part it LGTM. I guess its not the cleanest, as its
breaking the StorageHandler abstraction. Probably cleaner to add some hook to
StorageHandler interface, but due to backward compatibility, its probably not
worth it for this use-case.

> 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.
