> Currently NFS gateway closes an output stream after it's idle for certain period (e.g.,
10 seconds). The subsequent writes to the stream will fail. 
> This JIRA is to track the change to reopen an output stream to the same file to append
new data. This makes it possible for the application to directly stream data to HDFS.
