Subject [jira] [Commented] (YARN-6741) Deleting all children of a Parent Queue on refresh throws exception
Date Tue, 18 Jul 2017 19:20:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-6741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16092038#comment-16092038

-----------------------------------------

[~sunilg],
Well i was not thinking of any explicit use case as such, but was just covering all possible
scenarios with the modification of the queue hierarchy. And technically there is nothing limiting
us in supporting this which aids in admin to manage/reduce the queues with minimal number
of operations.

> If we configure CS such that all  children of a parent queue are deleted and made as
a leaf queue, then {{refreshQueue}} operation fails when re-initializing the parent Queue
> {code}
>        // Sanity check
>       if (!(newlyParsedQueue instanceof ParentQueue) || !newlyParsedQueue
>           .getQueuePath().equals(getQueuePath())) {
>         throw new IOException(
>             "Trying to reinitialize " + getQueuePath() + " from "
>                 + newlyParsedQueue.getQueuePath());
>       }
> {code}
> *Expected Behavior:*
> Converting a Parent Queue to leafQueue on refreshQueue needs to be supported.
