> 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.
