> These two tests don't pass. Turns out the cause was interesting.
> We added a workaround for case where procedure WAL could have procs out of order.
> HBASE-18216 [AMv2] Workaround for HBASE-18152, corrupt procedure WAL
> If we find a procedure that is not 'increasing' -- of a later timestamp or procid --
then we'd skip the application of the 'old' proc. The workaround was until we figure in what
scenarios we can write procedures out of order (seems to be rare and high-concurrency... TBD).
> These two tests trip FAILs and ROLLBACKs (double delete of table or disable of an already
disabled table). They are good tests. But procedures that get marked FAIL or ROLLEDBACK will
have procids that are less than current. Makes it so we skipped adding the ROLLBACK and so
finishing up the procedure.
