Subject [jira] [Comment Edited] (HBASE-18366) Fix flaky test hbase.master.procedure.TestServerCrashProcedure#testRecoveryAndDoubleExecutionOnRsWithMeta

----------------------------------------------------------------

bq. there is a RS with highest version coming in. We should move all system tables to this
new RS

Concern here is if one new node with higher version is added to the cluster, all system table
regions will be moved to this node. Subsequent addition of new nodes with same version as
previous one will not have any affect but these regions will only be moved (if at all) by
load balancer or by user.

> It worked for a few days after enabling it with HBASE-18278. But started failing after
commits:
> 6786b2b
> 68436c9
> 75d2eca
> 50bb045
> df93c13
> It works with one commit before: c5abb6c. Need to see what changed with those commits.
> Currently it fails with TableNotFoundException.
