[jira] [Created] (HADOOP-18324) Interrupting RPC Client calls can lead to thread exhaustion

Owen O'Malley created HADOOP-18324:
--------------------------------------

             Summary: Interrupting RPC Client calls can lead to thread exhaustion
                 Key: HADOOP-18324
                 URL: https://issues.apache.org/jira/browse/HADOOP-18324
             Project: Hadoop Common
          Issue Type: Bug
          Components: ipc
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently the IPC client creates a boundless number of threads to write the rpc request to the socket. The NameNode uses timeouts on its RPC calls to the Journal Node and a stuck JN will cause the NN to create an infinite set of threads.
