Charles Lamb updated HDFS-6392:
-------------------------------
Attachment: HDFS-6392.3.patch
Yi, you are right about getWrappedStream(). I forgot that your implementation
in Crypto{In,Out}putStream delegated #hflush and #hsync down. I also removed
the code in HdfsDataInputStream#getWrappedStream().
I believe the latest .3 patch addresses all of yours and Andrews concerns.
