chunhui shen commented on HBASE-8189:
-------------------------------------
It seems difficult because merge_region command need encoded region name,
however table regions are difficult to obtain through the curren scripts.
Therefore, there is no test for region-oriented commands, e.g. Move, Assign,
Unassign, Split/Compact region
> Shell commands of online region merge

> Usage:
> hbase> merge_region 'ENCODED_REGIONNAME', 'ENCODED_REGIONNAME'
> hbase> merge_region 'ENCODED_REGIONNAME', 'ENCODED_REGIONNAME', true
