Subject [jira] [Commented] (DRILL-2699) Collect all cleanup errors before reporting a failure to the client
Date Tue, 30 Jun 2015 22:08:04 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2699?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14609161#comment-14609161

Deneche A. Hakim commented on DRILL-2699:
-----------------------------------------

as part of DRILL-3052 and DRILL-3066 fragments won't report the failure to the foreman until
they finish cleaning up.
Once DRILL-3167 is merged, the Foreman will wait for all fragments to report back before the
Foreman reports back to the user, but the Foreman still only reports the "original" error
to the user and all other failures are suppressed. Will this address this issue, or do we
need to actually report all failures to the end user too ?

> If a query fails, the fragments and foreman should make sure to collect all failures
and report them back to the client. Some known places where this isn't respected:
> - If a fragment fails, it will report the failure to the foreman before cleaning up.
Any failure that happens in the cleanup process will be dropped by the foreman.
> - If multiple fragments fail, the Foreman will only report to the user the first failure
it received and close immediately. All other failures will be dropped.
