--------------------------------
Summary: Should update maxQueueSize when refresh call queue
Key: HADOOP-15253
URL: https://issues.apache.org/jira/browse/HADOOP-15253
Project: Hadoop Common
Issue Type: Improvement
Reporter: Tao Jie
Assignee: Tao Jie
When calling {{dfsadmin -refreshCallQueue}} to update CallQueue instance,
{{maxQueueSize}} should also be updated.
In case of changing CallQueue instance to FairCallQueue, the length of each
queue in FairCallQueue would be 1/priorityLevels of original length of
DefaultCallQueue. So it would be helpful for us to set the length of callqueue
to a proper value.
