Jason Lowe commented on YARN-6195:
----------------------------------
Thanks for updating the patch! At first I thought we had a potential for an
NPE in CSQueueUtils since there's this comment at the top:
{code}
/**
* Update partitioned resource usage, if nodePartition == null, will update
* used resource for all partitions of this queue.
*/
public static void updateUsedCapacity(final ResourceCalculator rc,
{code}
However in practice all the callers translate a null label to the no label enum
so we're good. Looks like we'd have NPE problems even before this patch if
nodePartition really was null, so that's a bad comment unrelated to this patch.
+1 for the latest patch. I'll commit this early next week if there are no
objections.
