Hemanth Yamijala commented on HADOOP-4373:
------------------------------------------
I incorporated the first two comments.
The last one I've not done. One reason is that a check for capacity percentages
is already done in HADOOP-4178 which is committed to trunk. Unfortunately, it
does not check for zero capacities. Hence two patches will need to be generated
to handle this - one for Hadoop 0.19, and one for trunk. Since it is only error
handling, I am thinking it is not worth that much effort.
The second is, specifying a value of zero for guaranteed capacity, along with
this patch, I think makes a nice way to disable a queue. Arguably, this is
better done by explicitly having a configuration parameter for enabling /
disabling a queue. But until that comes, I am thinking this is a nice side
effect to have.
