Date Fri, 13 Feb 2015 05:48:11 GMT

Jing Zhao updated HDFS-7793:
    Attachment: HDFS-7793.000.patch

Thanks for working on this, Bo! 

I also spent some time on this and got a very initial patch. The patch currently converts
DataStreamer to a static class, but still needs more code cleanup and extra check on various
synchronization scenarios. Please see if this patch can help and save you some time.

> As proposed by [~jingzhao], [~szetszwo] and discussed with [~zhz] in HDFS-7729, it would
be great to refactor DFSOutputStream first and separate DataStreamer out of it, before we
enhance it to support the stripping layout. [~umamaheswararao] suggested we have this issue
to handle the refactoring. Thanks.
