Josh Elser commented on HBASE-18134:
------------------------------------
Re-reading my notes and found an important detail I missed. The thought process
is that, after a Region is opened by a RegionServer, all other code paths which
will change that Region's size on HDFS would be covered by HBASE-18133.
So, instead of having a chore to periodically read+queue-for-send size reports
for Regions, we just queue a size report after the Region is opened. I believe
this completely eliminates the need for the FileSystemUtilizationChore.

> On the heels of HBASE-18133, we need to put some thought into whether or not
> there are cases in which the RegionServer should still report sizes directly
> from HDFS.
> The cases I have in mind are primarily in the face of RS failure/restart.
> Ideally, we could get rid of this chore completely.
