testfixer0 updated HADOOP-16847:
--------------------------------
Description: The method `testNegativeGroupCaching` can fail if the
iteration order of HashSet changes. So, this PR proposes to modify HashSet to
LinkedHashSet for a deterministic order (was: -private static Set<String>
allGroups = new HashSet<String>();
-private static Set<String> blackList = new HashSet<String>();
+private static Set<String> allGroups = new LinkedHashSet<String>();
+private static Set<String> blackList = new LinkedHashSet<String>();)
> Test can fail if HashSet iterates in a different order
