Subject [jira] [Commented] (HBASE-19505) Disable ByteBufferPool by default at HM
Date Wed, 13 Dec 2017 18:20:00 GMT

stack commented on HBASE-19505:

An option to disable sounds good. Default to enabling bytebufferpool on master if it is carrying
ANY regions but if you think only if system+user tables, thats fine too.

HM do not have any regions by default.  So we can make this pool OFF in HM side. Still add
a config to turn this ON.
