stack commented on HBASE-15406:
-------------------------------
To be more clear, -1 on a patch that has master doing a rollback of a state set
by external administrator's tool. HBCK already leaves the cluster in a state of
disequilibrium when killed mid-processing... Usual way this is addressed is
HBCK gets rerun... not master does cleanup.
On the patch, the admin additions look useful. The serialization of data to zk
needs to be a pb a/ PBUF Magic as preface.... See other places where we do zk
serialization.
> Split / merge switch left disabled after early termination of hbck

> 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.
