             Summary: Add option to allow multiple threads making calls on same RPC client not retry serially
                 Key: HADOOP-12645
                 URL: https://issues.apache.org/jira/browse/HADOOP-12645
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Chang Li
            Assignee: Chang Li


Current multiple threads making calls on same RPC client retry serially. For example, when a first call starts for retrying for 10 minutes, second and third and fourth calls called in during this time will get queued up. After 1st call fail, those second, third and fourth call will still unwisely go ahead serially to do the 10 minutes retry and fail. Propose to add a optional setting, default to false, but when enabled will allow those queued up following calls to fail without wasting time to retry.
