> The test has been passing consistently on the "4.*-HBase-0.98" branches. However, it
has been flapping pretty regularly on the master branch and the "4.*-HBase-1.1" branches.
> I ran the test locally a few number of times and it did flap. I did notice that in cases
where it failed, the logs also had a RegionOpeningException. 
> For example:
> {code}
> org.apache.hadoop.hbase.exceptions.RegionOpeningException: Region TEST_TABLET000060,\x07\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00,1479426366023.04f765e5d906bbd193b38a9f8c20e478.
