> We recently added to hbck2 a check of the cluster version it is to go against. This means a getClusterMetrics call with the option HBASE_VERSION set.
> In testing, trying to fix a failed namespace assign on startup, hbck2 was shut out with a "PleaseHoldException".
> Let the getClusterMetrics call happen even during startup... so tooling can probe Master state externally.
