Subject [jira] [Commented] (HBASE-8450) Update hbase-default.xml and general recommendations to better suit current hw, h2, experience, etc.
Date Wed, 22 May 2013 03:52:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13663737#comment-13663737
] 

stack commented on HBASE-8450:
------------------------------

Let me put back major compactions on a week period for now.  I added jitter of 0.5 so hopefully
the major compactions are spread over the week rather than all happening together monday morning
just as the load is coming on.

Let me fix the tests broke by changed defaults and post another patch.

> 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.
