Andrew Purtell commented on HBASE-22862:
----------------------------------------
Yes it's branch-1 only. There is some compatibility code in FixedFileTrailer in
later versions that still understands the classname but the class itself has
been removed.
Does the VisibleForTesting annotation mean the method with the weird and
possibly incorrect comparison is only used in unit tests?
