Elliott Clark commented on HBASE-8450:
--------------------------------------
bq.hbase.hstore.compactionThreshold=5: we now have a better compaction
algorithm, maybe it's worth keeping more files around and be more efficient
about the whole process?
I would disagree here. Better to choose fewer files and be less spiky on io
and latency. Though upping the number of blocking files seems ok.
* Lower the number of versions on a table by default. Most new users don't
really need three. I think putting it at 2 by default helps users know the
feature is there without wasting space.
* Turn on bloom filters. (ROW)
> Update hbase-default.xml and general recommendations to better suit current
> hw, h2, experience, etc.

> This is a critical task we need to do before we release; review our defaults.
> On cursory review, there are configs in hbase-default.xml that no longer have
> matching code; there are some that should be changed because we know better
> now and others that should be amended because hardware and deploys are bigger
> than they used to be.
> We could also move stuff around so that the must-edit stuff is near the top
> (zk quorum config. is mid-way down the page) and beef up the descriptions --
> especially since these descriptions shine through in the refguide.
> Lastly, I notice that our tgz does not "include" an hbase-default.xml other
> than the one bundled up in the jar. Maybe we should make it more accessible.
