--------------------------------------
Here's an example of the "holding pattern" message.

> Key: HBASE-24292
> URL: https://issues.apache.org/jira/browse/HBASE-24292
> Project: HBase
> Issue Type: Bug
> Components: master, Region Assignment
> Affects Versions: 2.3.0
> Reporter: Nick Dimiduk
> Priority: Major
>
> The master schedules a SCP for the region server hosting meta. However, due
> to a misconfiguration, the cluster cannot make progress. After fixing the
> configuration issue and restarting, the cluster still cannot make progress.
> After the configured period (15 minuets), the master enters a "holding
> pattern" where it retains Active master status, but isn't taking any action.
> This "brown-out" state is toxic. It should either keep trying to make
> progress, or it should abort. Staying up and not doing anything is the wrong
> thing to do.
