Andrew Purtell created HBASE-13676:
--------------------------------------

             Summary: TestRegionServerHostname#testInvalidRegionServerHostnameAbortsServer
is failing
                 Key: HBASE-13676
                 URL: https://issues.apache.org/jira/browse/HBASE-13676

          Issue Type: Bug
    Affects Versions: 2.0.0, 1.1.0

Failed tests:

This is because the exception message is not what the test expects. We want a string containing
"Failed resolve of " + invalidHostname, what I have is "java.net.BindException: Problem binding
to hostAddr.invalid/198.105.244.228:0 : Cannot assign requested address"

This is because my ISP is "helpfully" providing A records for invalid DNS records.

The test should be made more general to capture this kind of failure too.
