Description

When testExceptionOnBackgroundRefreshHandled is run individually, it reliably fails. It seems like a fundamental bug in the test or groups caching.

A similar issue was dealt with in HADOOP-13375. cheersyang, do you have any insight into this?

This test case was added in HADOOP-13263.
