Ahmed Hussein resolved HDFS-10961.
----------------------------------
    Resolution: Cannot Reproduce

Similar to HDFS-10498, for branches trunk and branch-2.10, I could not 
reproduce the failure.
 My intuition is that it happens due to slow down on the server as a side 
effect of some other Units in parallel.
I am going to close this Jiras for now.
