Alejandro Abdelnur commented on YARN-521:
-----------------------------------------
* Javadocs on AMRMClient.ContainerRequest class are not correct, @params should
go in the constructor javadoc
* AMRMClient.ContainerRequest constructor. the {{(!relaxLocality && racks ==
null && nodes == null) }} check seems incomplete, what happen if giving a [0]
array or an array with NULL values. I know we are not doing these kind of check
in other places, so maybe a diff JIRA to do them in all the AMRMClient API?
* in AMRMClientImpl.addContainerRequest() it seems we are doing more than the
JIRA accounts for. renaming allRacks to dedupedRacks & inferring racks from
nodes. Unless I'm missing something, this should be done in a diff JIRA.
