Subject [jira] Commented: (MAPREDUCE-893) Provide an ability to refresh queue configuration without restart.
Date Thu, 17 Sep 2009 16:12:57 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756608#action_12756608

Vinod K V commented on MAPREDUCE-893:

bq. I think we should remove the properties that are no longer supposed to be capacity-scheduler.xml
and add a new file - something like mapred-queues-for-cs.xml.template. This would only be
for documentation purposes and we could comment that users of capacity scheduler can rename
this to mapred-queues.xml adding more queues etc, based on the documentation provided. Works
I am not taking this up in this JIRA. Can do it in a follow up.

> While administering a cluster using multiple queues, administrators feel a need to refresh
queue properties on the fly without needing to restart the JobTracker. This is partially supported
for some properties such as queue ACLs (HADOOP-5396) and state (HADOOP-5913). The idea is
to extend the facility to refresh other queue properties as well, including scheduler properties.
