Zsolt Venczel commented on HDFS-13731:
--------------------------------------
Thanks for the review [~xiaochen]!
In my latest patch I added the protection you suggested. Also I did some
additional analysis and I found that the rest of the failure scenarios were due
to the same ConcurrentModificationException therefore I removed the changes
from the tests.
Could not reproduce any failure after I've applied the patch on the latest
trunk:
