Tsz Wo Nicholas Sze updated HDFS-7738:
--------------------------------------
    Attachment: h7738_20150206.patch

Thanks, Konstantin.
# Java enum is implicitly static, i.e. there is no non-static enum.
# done
# yes, it is better to have some random test.  Let me decrease the number of blocks from 1000
to 100 so that the overhead is much smaller.
# Sure, let's use my previous version of the test.  Will file a new JIRA for the new test.
 BTW, how it fails? 

Here is a new patch: h7738_20150206.patch
