> The test o.a.h.hdfs.server.namenode.TestNNStorageRetentionManager uses a
> HashMap(dirRoots) to store the root storages to be mocked for the purging
> test, which does not have any predictable order. The directories needs be
> purged are stored in a LinkedHashSet, which has a predictable order. So, when
> the directories get mocked for the test, they could be already out of
> the order that they were added. Thus, the order that the directories were
> actually purged and the order of them being added to the LinkedHashList could
> be different and cause the test to fail.
