> testRefreshUserToGroupsMappingsWithFileSystemBasedConfigurationProvider fails with the
following error:
> {noformat}
> java.lang.AssertionError: null
> 	at org.junit.Assert.fail(Assert.java:92)
> 	at org.junit.Assert.assertTrue(Assert.java:43)

> 	at org.apache.hadoop.yarn.server.resourcemanager.TestRMAdminService.testOrder(TestRMAdminService.java:104)
> {noformat}
> Line Numbers will be inconsistent as I was testing to run it in a particular order. But
the Line on which the failure occurs is
> {code}
> Assert.assertTrue(groupBefore.contains("test_group_A")
>         && groupBefore.contains("test_group_B")
>         && groupBefore.contains("test_group_C") && groupBefore.size()

> {code}
> testRMInitialsWithFileSystemBasedConfigurationProvider() and
> testRefreshUserToGroupsMappingsWithFileSystemBasedConfigurationProvider()
> calls the function {{MockUnixGroupsMapping.updateGroups();}} which changes the list of
userGroups.
> testRefreshUserToGroupsMappingsWithFileSystemBasedConfigurationProvider() tries to verify
the groups before changing it and fails if testRMInitialsWithFileSystemBasedConfigurationProvider()
already ran and made the changes.
