Sandy Ryza commented on YARN-1774:
----------------------------------
Thanks for picking this up Anubhav.
A couple nits:
* In the test, writing out the xml file can be avoided.
scheduler.getQueueManager().getLeafQueue("parent.child.granchild1", true) will
create the queue and its parents.
* If an app is rejected in this way, "Application rejected by queue placement
policy" will be printed out, which is not entirely accurate. I'm not sure what
the cleanest way to fix this, but perhaps either merging assignAppToQueue into
addApplication or getLeafQueue could throw an exception that gets caught in
addApplication.
* "Cannot find queue named " + queueName + " or its not a leaf queue". This
won't occur when the queue can't be found, only when it can't exist as a leaf
queue given the current hierarchy. Also, need an apostrophe in the "it's".
