Anoop Sam John commented on HBASE-8450:
---------------------------------------
[~stack] We have changed the config values in xml file. Still in the code, some
places it refers to the old values. Sorry missed this point in the review.
{code}
HConstants
public static final float HFILE_BLOCK_CACHE_SIZE_DEFAULT = 0.25f;
MemStoreFlusher
private static final float DEFAULT_LOWER = 0.35f;
{code}
It might look confusing for developers later. We can correct this?
> 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.
