Miklos Gergely commented on AMBARI-17004:
-----------------------------------------
AmbariLdapDataPopulatorTest.testSynchronizeExistingLdapGroups_removeDuringIteration
AmbariLdapDataPopulatorTest:328-329 specifies that getLdapGroups should return
groupDtos created at AmbariLdapDataPopulatorTest:306 for both group1 and
group2. At AmbariLdapDataPopulator:325 it grabs the first element of groupDtos,
and if it's not group1Dto but group2Dto then it will return an empty set for
the getMemberAttributes() at AmbariLdapDataPopulator:374 thus
getLdapGroupByMemberAttr("group2") will not be invoked, which is expected.
Suggested solution: separate groupDto for group1 and group2, containing only
the given group.
> Unit tests failing because of the order of hash sets/maps

> Project: Ambari
> Issue Type: Bug
> Reporter: Miklos Gergely
>
> Some unit tests are failing because they depend on the order elements are
> returned by the iterator of a HashSet/HashMap. Usually they are small (2-3
> entries), so they may easily produce good results. Still in other
> environments they fail as the order the elements are returned from a
> HashSet/HashMap may depend on the JVM used.
> The tests will be described in the comments.
