Chris Li commented on HADOOP-10285: ----------------------------------- The service RPC queue is so that we can get through in the event the clientRPC queue is completely full. bq. We can address it in a separate Jira if it makes sense, but ideally in the same release so we don't have to support RefreshCallQueueProto forever. Makes sense, I'll give that a shot. > Admin interface to swap callqueue at runtime > -------------------------------------------- > > Key: HADOOP-10285 > URL: https://issues.apache.org/jira/browse/HADOOP-10285 > Project: Hadoop Common > Issue Type: Sub-task > Reporter: Chris Li > Attachments: HADOOP-10285.patch, HADOOP-10285.patch, > HADOOP-10285.patch, bisection-test.patch, bisection-test.patch, > bisection-test.patch, bisection-test.patch, bisection-test.patch > > > 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 -- This message was sent by Atlassian JIRA (v6.1.5#6160)
