[jira] [Commented] (HIVE-23619) HiveServer2 should retry query if the TezAM running it gets killed

    [ https://issues.apache.org/jira/browse/HIVE-23619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17126887#comment-17126887 ] 

David Mollitor commented on HIVE-23619:
---------------------------------------

Does this not already happen?  I am somewhat knew to Tez, but typically AMs are re-launched automatically (at least once) by YARN if they die.

> If the TezAM was running a query and it gets killed because of external factors like node going node, HS2 should retry the query in different TezAM.
