public void testCleanerDoesNotDeleteDirectoryWithLateAddedFiles()
                                                         throws IOException

While cleaning a directory, all the files in the directory may be deleted, but there may be another file added, in which case the directory shouldn't be deleted.

Throws:

IOException - on failure

testNoExceptionFromDirectoryWithRacyChildren

public void testNoExceptionFromDirectoryWithRacyChildren()
                                                  throws Exception

The cleaner runs in a loop, where it first checks to see all the files under a directory can be deleted. If they all can, then we try to delete the directory. However, a file may be added that directory to after the original check. This ensures that we don't accidentally delete that directory on and don't get spurious IOExceptions.

This was from HBASE-7465.

Throws:

Exception - on failure
