Ben Lau commented on HBASE-13991:
---------------------------------
The HBase master doesn't write much to disk compared to region servers/data
nodes. Yes, this change is mostly to the filesystem layout. We may use the
'humongous' flag for other things in the future but currently it is only used
to determine the layout.
