> System Regions on the Master is broken

> Key: HBASE-19785
> URL: https://issues.apache.org/jira/browse/HBASE-19785
> Project: HBase
> Issue Type: Sub-task
> Reporter: Michael Stack
> Priority: Major
>
> The parent issue broke our being able to host system regions only on the
> Master.
> This broke a few tests that depend on this ability. Two of the below actually
> enable system regions on the Master for the test run. The remainder is the
> test that make sure this works.
> TestMultiParallel
> TestRegionsOnMasterOptions
> TestRegionServerReadRequestMetrics
> Parent changed the startup order. System regions and Master-as-a-RegionServer
> are having issues because we wait for regionservers to check in before
> completing Master startup which gets interesting when Master is supposed to
> act like a RegionServer. Previously, Master startup was off in a background
> thread.
> Needs more thought but not required for beta-1.
