Description

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:

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

Expectation is that the split / merge switches should be restored to default value after hbck exits.
