----------------------------------------
{quote}The flakey-finder fingered the above commit as breaking the split test.

The latest QA in HBASE-19703 is shown below. The TestSplitTableRegionProcedure
is already in flaky. [~uagashe] Do you intent to fix the test totally? I'm +1
to your patch even if the TestSplitTableRegionProcedure is still flaky.
