> User.createUserForTesting should not reset UserProvider.groups every time if
> hbase.group.service.for.test.only is true

>
> Key: HBASE-26662
> URL: https://issues.apache.org/jira/browse/HBASE-26662
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.5.0, 3.0.0-alpha-2, 2.4.9, 2.6.0
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Major
> Fix For: 2.5.0, 2.6.0, 3.0.0-alpha-3, 2.4.10
>
>
> The _if check_ below will always unnecessarily reset static var
> _UserProvider.groups_ to a newly created instance of TestingGroups every time
> `User.createUserForTesting` is called.
> {noformat}
> if (!(UserProvider.groups instanceof TestingGroups) ||
> conf.getBoolean(TestingGroups.TEST_CONF, false)) {
> UserProvider.groups = new TestingGroups(UserProvider.groups);
> }
> {noformat}
> For tests creating multiple {_}test users{_}, this causes the latest created
> user to reset _groups_ and all previously created users would now have to be
> available on the {_}User.underlyingImplementation{_}, which not always will
> be true.
