Subject [jira] [Created] (HADOOP-15253) Should update maxQueueSize when refresh call queue
Date Fri, 23 Feb 2018 02:30:01 GMT
Tao Jie created HADOOP-15253:

             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.
