[jira] [Commented] (HIVE-20723) Allow per table specification of compaction yarn queue

["Stamatis Zampetakis (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-20723?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17482124#comment-17482124 ] 

Stamatis Zampetakis commented on HIVE-20723:
--------------------------------------------

It seems that it was possible to select a queue per table without implementing the change here by using {{compactor.mapred.job.queue.name}} inside table properties.

[~ekoifman] [~saurabhseth] is there any particular reason of why you chose to do it via the {{compactor.hive.compactor.job.queue}} property? The problem is that with the change in this JIRA the old property gets overwritten and doesn't have the desired effect so it kinda breaks backward compatibility.

> Currently compactions of full CRUD transactional tables are Map-Reduce jobs submitted to a yarn queue defined by hive.compactor.job.queue property.
> If would be useful to be able to override this on per table basis by putting it into table properties so that compactions for different tables can use different queues.
>  
> There is already ability to override other compaction related configs via table props, though this will need additional handling to set the queue name {{CompactorMr.createBaseJobConf}}
