Comment 3 Michael Burman 2019-04-07 14:39:57 UTC

QE can't reproduce this report. Can you please be more specific with the steps. You mentioned update cluster role, which role?

Comment 4 Sharon Gratch 2019-04-16 10:46:48 UTC
@sasundar, I posted a patch that may fix the issue and is based on the exception stack trace only.
So please try to reproduce the exception to make sure that this fix really solves the problem.
