Elliott Clark commented on HBASE-9775:
--------------------------------------

bq.Any chance of running with old CMS settings? Let's eliminate as many variables as we can.
This is an exact replica of the settings that we're using on our IT test rig.  Same heap space,
same gc, and the same number of map tasks per server.  The only difference between the clusters
is that our IT test cluster has 6 region servers this has 77.
