Anu Engineer commented on HDFS-12890:
-------------------------------------
[~shashikant] Thanks for getting this patch done. It looks good overall.
I have a minor concern, suppose the XceiverClientHandler#exceptionCaught is
invoked, do you see a possibility of a deadlock? In other words, If we get
around 256 or 100 exceptionCaught invokes, there will be no thread left to
unlock the semaphore, and hence no more requests can be made. Does my concern
look real?
