Heng Chen updated HBASE-15406:
------------------------------
Attachment: test.patch
with the test.patch, do as follows:
1. bin/hbase hbck -abort -disableSplitAndMerge // this will abort hbck with
switches left.
2. then open the shell, try splitormerge_switch command, you will see.
{code}
hbase(main):001:0> splitormerge_switch 'SPLIT', true
ERROR: java.io.IOException: Can't set splitOrMerge switch due to old lock!

3. bin/hbase hbck -disableSplitAndMerge
4. try 'splitormerge_enabled' command, you will see the switch set back.

> URL: https://issues.apache.org/jira/browse/HBASE-15406
> Project: HBase
> Issue Type: Bug
> Reporter: Ted Yu
> Priority: Critical
> Fix For: 2.0.0, 1.3.0, 1.4.0
>
> Attachments: HBASE-15406.patch, HBASE-15406.v1.patch,
> HBASE-15406_v1.patch, test.patch, wip.patch
>
>
> 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.
