Xiao Chen commented on HDFS-7553:
---------------------------------

Jenkins failed desperately on the patch reproducing the exception.
Please review patch 2. After that I think we can rerun Jenkins against patch 2 
since the last run was 1 month ago (or modified patch 3 based on comments). 
Thank you!
