> This is because upgrading Ambari from an older version to 2.5.1 right now
> will update storm-env only if Storm is present and the cluster is Kerberized.
> In this case, Ambari was upgraded to 2.5.1, EU was performed to HDP 2.6.1,
> and then the cluster was kerberized; kerberization has no trigger to change
> configs and will not invoke Stack Advisor.
> The fix is to relax the constraint so that Ambari Upgrade adds the exports to
> storm-env as long as Storm is present. If Storm is added after the fact, then
> its definition inside of HDP 2.6 (plus Stack Advisor) will handle that use
> case.
