Suresh Srinivas commented on HDFS-4200:
---------------------------------------
bq. Forgot to mention, I believe there's a corner case in 2.0.3 that causes the
dfs client to deadlock, you may hit this when running your test.
I am not planning to test for or fix any deadlock. The patch is just reducing
the size of synchronized section and doing some much needed refactoring in the
code.
Todd, do you have any further comments?
