[jira] [Commented] (HBASE-23932) Region Normalizer is disruptive while running hbck2 fix meta

["Nick Dimiduk (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-23932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17051705#comment-17051705 ] 

Nick Dimiduk commented on HBASE-23932:
--------------------------------------

Right now, the default run interval for normalizer is 5 minutes. It's the same interval as the balancer, but maybe that's too aggressive for this type of work?

Probably the normalizer should only consider regions in the {{OPEN}} state.

> While hbck2 runs through fixes to meta, the Normalizer kicks in to "help". Mostly this is fine, however, things get confused when {{fixMeta}} is action on a region and then the normalizer decides to do something as well. Could be we advise operators disable normalizer while running hbck2, but would be better if the normalizer was less aggressive, so that there's fewer flags to fiddle.
