    Description

      When an unstable write arrives, the following happens:
      1. retrieves the OpenFileCtx
      2. create asyn task to write it to hdfs

      The race is that, the OpenFileCtx could be closed by the StreamMonitor. Then step 2 will simply return an error to the client.

      This is OK before streaming is supported. To support data streaming, the file needs to be reopened.
