     [ https://issues.apache.org/jira/browse/HADOOP-10285?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Chris Li updated HADOOP-10285:
------------------------------

    Description: 
We wish to swap the active call queue during runtime in order to do performance tuning without restarting the namenode.
This patch adds the ability to refresh the call queue on the namenode, through dfsadmin -refreshCallQueue
