[jira] [Commented] (HIVE-9460) LLAP: Fix some static vars in the operator pipeline

    [ https://issues.apache.org/jira/browse/HIVE-9460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16590958#comment-16590958 ] 

Shyam Rai commented on HIVE-9460:
---------------------------------

In a scenario when LLAP is configured but not active, buggy or disabled, setting *hive.execution.mode=llap;* does not fail any query but runs it in container mode. I understand that it might be the only available or  the fallback mechanism, however, wouldn't it be worth it to add the information about default container mode ?

Running the jobs from ODBC/JDBC apps might not have the visibility on how the jobs are running (container vs llap).
