[jira] [Created] (HADOOP-11295) RPC Reader thread can't be shutdowned if RPCCallQueue is full

Ming Ma created HADOOP-11295:
--------------------------------

             Summary: RPC Reader thread can't be shutdowned if RPCCallQueue is full
                 Key: HADOOP-11295
                 URL: https://issues.apache.org/jira/browse/HADOOP-11295
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Ming Ma


You RPC server is asked to stop when RPCCallQueue is full, {{reader.join()}} will just wait there. That is because

1. The reader thread is blocked on {{callQueue.put(call);}}.
2. When RPC server is asked to stop, it will interrupt all handler threads and thus no threads will drain the callQueue.
