Subject [jira] [Commented] (HBASE-12629) Remove hbase.regionsizecalculator.enable from RegionSizeCalculator
Date Thu, 18 Dec 2014 04:16:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14251151#comment-14251151

Enis Soztutar commented on HBASE-12629:

bq. 1) Just removing that rscalc config so we have one knob using the the HBASE-12590 deskew
is used.
bq. 2) An alternative where we refactor instead of remove and have the HBASE-12590 patch decides
on the to pick the "ClusterStatusRegionSizeCalculator" if enabled or "AlwaysZeroRSCalc" if
not enabled. We'd combine HBASE-12590 and HBASE-10413's features into one config knob (instead
of what currently would be two). If after some testing HBASE-12590 works nicely, I think I'd
want it on by default as well.
I think it makes sense to combine the knobs. We do not need this particular config option
per se, as long as we still have a way to disable it in case something goes wrong.

> The RegionSizeCalculator has a option to disable it.  It is on by default and end-to-end
use with it disabled is not tested or used anywhere except for a simple unit test.  This removes
