Subject [jira] [Commented] (HBASE-15406) Split / merge switch left disabled after early termination of hbck
Date Wed, 15 Jun 2016 04:18:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15331115#comment-15331115
] 

stack commented on HBASE-15406:
-------------------------------

Sorry. Late to the reply.

My -1 comment was against a system that had a tool set a state that master would cleanup under
certain conditions. I was against complicating the master role to deal with weird tooling
behaviors. To keep things manageable and contained, I suggested let the tool do the fix up/clean
up.

Enis shows up with a general category under which we could gather a fleet of operation types
that could impinge on master state that keeps-it-simple for the master. I'm in favor of his
suggestion.

Sorry if I ended up making more work for you [~chenheng]

> This was what I did on cluster with 1.4.0-SNAPSHOT built Thursday:
> Run 'hbase hbck -disableSplitAndMerge' on gateway node of the cluster
> Terminate hbck early
> Enter hbase shell where I observed:
> {code}
> hbase(main):001:0> splitormerge_enabled 'SPLIT'
> false
> 0 row(s) in 0.3280 seconds
> hbase(main):002:0> splitormerge_enabled 'MERGE'
> false
> 0 row(s) in 0.0070 seconds
> {code}
> Expectation is that the split / merge switches should be restored to default value after
hbck exits.
