Jonathan Hsieh commented on HBASE-11339:
----------------------------------------
bq. The master's built in splitting was still available even if there was no MR
runtime that could run the replay tool.
If you were ok with 10 hr downtimes due to recovery (back then no meta first
recovery), the sure. For large deployments that MR for this was critical and
not really optional.
bq. Stage = JIRA issue.
sgtm.
bq. If I read the above correctly we are looking at 2.0 as a possible release
for shipping this feature? I suggest we communicate the feature status as
experimental for the whole release line, i.e. until 2.1, like what we have done
with the cell security features in the 0.98 line.
Yes -- trunk is 2.0 and new features should only land in trunk and yes, we
would note it as experimental until all pieces are in and some hardening as
taken place. . Ideally, all major features would be experimental in their
first release. If we follow through with having 2.0 -> 2.1 be like will be like
0.92 -> 0.94 or 0.96->0.98, then following the cell security approach for
experimental status sounds good to me.

> It's quite useful to save the medium binary data like images, documents
> into Apache HBase. Unfortunately directly saving the binary MOB(medium
> object) to HBase leads to a worse performance since the frequent split and
> compaction.
> In this design, the MOB data are stored in an more efficient way, which
> keeps a high write/read performance and guarantees the data consistency in
> Apache HBase.
