----------------------------------

             Summary: RPC call hangs when server side CPU overloaded
                 Key: HADOOP-13404
                 URL: https://issues.apache.org/jira/browse/HADOOP-13404
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Peter Shi


In our reliability test, in namenode, inject fault like cpu 100% consumed, after fault injection,
for existing connection, all the request will hangs forever, not timeout. for new coming connection,
it will failover to another namenode in HA deployment.

There is no timeout mechanism for calls on established connection.
