> Key: HADOOP-13189
> URL: https://issues.apache.org/jira/browse/HADOOP-13189
> Project: Hadoop Common
> Issue Type: Bug

>
> {{FairCallQueue}} divides {{callQueue}} into multiple (4 by default)
> sub-queues, with each sub-queue corresponding to a different level of
> priority. The constructor for {{FairCallQueue}} takes the same parameter
> {{capacity}} as the default CallQueue implementation, and allocates all its
> sub-queues of size {{capacity}}. With 4 levels of priority (sub-queues) by
> default it results in the total callQueue size 4 times larger than it should
> be based on the configuration.
> {{capacity}} should be divided by the number of sub-queues at some place.
