Added test for the shell. Tested patch on single node cluster via shell. Works 
as expected. Please review [~zghaobac], [~stack]

Nihal Jain commented on HBASE-17942:


I discovered a strange behavior while writing tests in the above patch.

It is easily reproducible: Just add following statement at the end of testcase: 
{{TestSplitTableRegionProcedure.testSplitTableRegionEmptyDaughter()}}
{code:java}
UTIL.getAdmin().modifyTable(UTIL.getAdmin().getDescriptor(tableName));
{code}
 The modify procedure succeeds but the future never returns and the test-case 
keeps running.

See the tail of the log:

[~vrodionov], [~stack ] This seems like a useful feature. Can I take this up?
