0.90.4 fixes two deadlocks (HBASE-4101 and HBASE-4077). Since then,

Below sounds like slowness. Can you thread dump the particular
regionserver and see what its up to? Is there other loading on the
system at the time? For example, loading on hdf

So the important part is:

And it seems to be coming from the hadoop security stack. From what I
can tell 0.2
