Subject [jira] [Commented] (HIVE-13280) Error when more than 1 mapper for HBase storage handler
Date Mon, 02 Oct 2017 16:27:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16188388#comment-16188388
] 

sandeep mehta commented on HIVE-13280:
--------------------------------------

I have tried by setting up {code} hbase.mapred.output.outputtable {code} but it's throwing
the same error but when I only try to insert one record into the table then it works properly
and no error. 
Even after the load job fails some of the data gets to the table anyways.

> If I do an ALTER CONCATENATE for aa_temp. And redo the query. Everything is fine because
there are only one mapper.
