Subject [jira] [Commented] (HBASE-15406) Split / merge switch left disabled after early termination of hbck
Date Fri, 15 Apr 2016 04:34:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15242415#comment-15242415

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

Hey [~chenheng] Thanks for working on this one.

You get the bit that our Admin API is public and that you can't change it. You can add methods
but not change existing ones?

I'm talking about the addition of the param here

	                                   final boolean skipLock,

Do an override instead?

Otherwise patch looks good.

> 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.
