Subject [jira] [Commented] (YARN-5746) The state of the parentQueue and its childQueues should be synchronized.
Date Mon, 31 Oct 2016 18:05:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5746?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15622889#comment-15622889

Xuan Gong commented on YARN-5746:
---------------------------------

Thanks for the review. [~ozawa] [~templedf] 
bq. I would like to suggest that we create new state, QueueState.NOT_FOUND, and return it
instead of returning null. What do you think?

I would like to keep null as the return value here.  In the design doc of YARN-5724, we will
create a State Machine for the queue, NOT_FOUND does not sound like a valid state for me.

Uploaded a new patch to address all other comments.

> The state of the parentQueue and its childQeues need to be synchronized. 
> * If the state of the parentQueue becomes STOPPED, the state of its childQueue need to
become STOPPED as well. 
> * If we change the state of the queue to RUNNING, we should make sure the state of all
its ancestor must be RUNNING. Otherwise, we need to fail this operation.
