------------------------------
If it still applies, no harm I'd say adding it. Should this bubble up to be a column family attribute some day?

stack commented on HBASE-1826:
------------------------------
I don't think that always necessary. IMO, there is a category of config. that is just exotic and that its ok if the only way you figure a behavior is configurable is by digging in code. If the 'exotic config' gets say, a mention or two on the mailing list, i.e. someone asks about whether such a facility were available, then I think the config. should graduate from exotic to hbase-default.xml.

(going through the list of issues)
Do we still want this? The patch looked ready back in september but it was never committed.

ryan rawson commented on HBASE-1826:
------------------------------------
I added this because i was testing performance of hdfs-200 with less replication factor to make it faster. It didn't end up working out well, so I more or less dropped it. I'm not sure its a feature we need exactly.
As for making it a CF attribute, that isn't gonna work because of the 1 hlog per RS covering multiple tables.

-------------------------------------------
Shouldn't hbase.regionserver.hlog.replication be documented in hbase-defaults.xml?
