Todd Lipcon commented on HDFS-955:
----------------------------------
HADOOP-6554 is the NPE on close. Sorry, I should have mentioned you need to fix
that by adding the appropriate if (thread != null) check. After fixing that,
the test fails on the reopen. Also, the test doesn't fail if you switch to only
one dfs.name.dir.
I'll take a look at your patch, thanks.
