Subject [jira] [Commented] (HBASE-16465) Disable region splits and merges, balancer, catalog janitor and normalizer during full backup
Date Thu, 25 Aug 2016 14:19:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16465?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15436957#comment-15436957

Vladimir Rodionov commented on HBASE-16465:
-------------------------------------------

On a large tables with many regions, snapshots (full backups) will be failing with high probability.
It has been discussed already many times. Unfortunately, there is no way to disable splits/merges
for a table. 

I can make this configurable through command line-arg (-disableSplits or similar). Question:
how does balancer and catalog janitor affects snapshots? Not clear to me.
