[jira] [Commented] (DRILL-2542) Killing a drillbit when a query is running results in hanging query

["Ramana Inukonda Nagaraj (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-2542?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14378748#comment-14378748 ] 

Ramana Inukonda Nagaraj commented on DRILL-2542:
------------------------------------------------

Looks like the behavior is different depending on which drillbits are killed- Foreman or otherwise.
In case of non foreman node the query hangs around with CANCELLATION_REQUESTED message.

In case of the foreman node drillbit process being killed there seems to be no change in the state of the query.  From the JDBC client or from the profiles page where its listed as RUNNING.
