Steve Loughran commented on HADOOP-11710:
-----------------------------------------

Looking at the code, it seems OK to me, so +1

However, I would recommend one change, which is in {{close()}}, move the 
close=true operation up immediately after the close check, just in case 
something in {{freeBuffers() }} raised an exception or the parent did -it'll 
stop a second close() call getting into a mess. This is not really related to 
the rest of the patch, except in the general "improve re-entrancy" context



> Make CryptoOutputStream behave like DFSOutputStream wrt synchronization
