>
> 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.
