stack commented on HBASE-11839:
-------------------------------
[~sergey.soldatov] No suggestion or comment, just encouragement. Thanks for
digging in here. I was thinking it was an issue w/ the first run of
TestRegionRebalance because a bunch of threads still hanging out after it
completes.... was trying to look there. I was going to also just try this:
{code}
diff --git
a/hbase-server/src/test/java/org/apache/hadoop/hbase/TestRegionRebalancing.java
b/hbase-server/src/test/java/org/apache/hadoop/hbase/TestRegionRebalancing.java
index fdcb00c..d158c2b 100644

Your finding sounds better than mine.
Anything you want to try? Anything you want to commit? Seems pretty easy to
reproduce but if you want to add a bit of debugging just say and I'll commit it
for you, np.
