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.
