Colin Patrick McCabe commented on HDFS-7836:
--------------------------------------------

Thanks, Chris.  I agree that \-Xmx == \-Xms is often a useful configuration.  It would be
interesting to get more information about how much change in those settings will be necessary
in general with off-heap.  We'll have to think about that.

I created a branch for this work, HDFS-7836.
