> If the masterprocwals have been removed -- operator error, hdfs dataloss, or
> because we have gotten ourselves into a pathological state where we have
> hundreds of masterprocwals too process and it is taking too long so we just
> want to startover -- then master startup will have a dilemma. Master startup
> needs hbase:meta to be online. If the masterprocwals have been removed, there
> may be no outstanding assign or a servercrashprocedure with coverage for
> hbase:meta (I ran into this issue repeatedly in internal testing purging
> masterprocwals on a large test cluster). Worse, when master startup cannot
> find an online hbase:meta, it exits after exhausting the RPC retries.
> So, we need a holding-pattern for master startup if hbase:meta is not online
> if only so an operator can schedule an assign for meta or so they can assign
> fixup procedures (HBASE-20786 has discussion on why we cannot just
> auto-schedule an assign of meta).
