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

             Summary: Race in NettyRpcConnection may cause call stuck in BufferCallBeforeInitHandler
forever
                 Key: HBASE-18199
                 URL: https://issues.apache.org/jira/browse/HBASE-18199
             Project: HBase
          Issue Type: Bug
          Components: IPC/RPC
    Affects Versions: 3.0.0, 1.4.0, 2.0.0-alpha-1
            Reporter: Duo Zhang
            Assignee: Duo Zhang
             Fix For: 3.0.0, 1.4.0, 2.0.0-alpha-2


Found this when implementing the POC of HDFS-9924.

The problem is that channel.writeAndFlush will find the first outbound handler before scheduling
the actual write task into event loop, so it is possible that when we actually execute the
write task, the first outbound handler has already been changed but the task still refers
to the old handler which has already been removed.
