Gabor Bota resolved HADOOP-15511.
---------------------------------
Resolution: Not A Problem
Sorry for the noise on this, as it turns out the test is working as expected.
The following happens:
* Tests a circular sequence of renames to verify that overwriting recently
* deleted files and reading recently created files from rename operations
* works as expected.
The first check of the directory (the first doTestRenameSequence) won't check
anything, but the followups are working as expected.

> The problem is that we should check that the srcdir is moved to dstdirs, so
> it should be check in nodirs. Right now nodirs parameter checks for
> directories which are completely unrelated to the cases, so this part of the
> test should be fixed to check for dirs that are related to the cases.
> Basically the nodirs should be equal to srcdirs in this case.
