Minor Description
if the bulkload dir contains "other folders" with a valid family name, LoadIncrementalHFile will throw an unmatched family name exception.
(In this case our test was running with the MR log dir pointing to the same bulkload dir)
Unmatched family names found: unmatched family names in HFiles to be bulkloaded: [_logs]; valid family names of table testMRIncrementalLoad_1423719217782 are: [info-A, info-B] Stacktrace
In theory we can add a second check to verify if the file inside the unmatched family is an hfile or not, and in case the folder doesn't contain hfiles we can skip that folder, and avoid the unmatched family exception.
