> hbck -o should not allow bypassing pre transit check by default
> ---------------------------------------------------------------
>
> Key: HBASE-28151
> URL: https://issues.apache.org/jira/browse/HBASE-28151
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.4.17, 2.5.5
> Reporter: Viraj Jasani
> Assignee: Rahul Kumar
> Priority: Major
> Fix For: 3.0.0-beta-2
>
>
> When operator uses hbck assigns or unassigns with "-o", the override will
> also skip pre transit checks. While this is one of the intentions with "-o",
> the primary purpose should still be to only unattach existing procedure from
> RegionStateNode so that newly scheduled assign proc can take exclusive region
> level lock.
> We should restrict bypassing preTransitCheck by only providing it as site
> config.
> If bypassing preTransitCheck is configured, only then any hbck "-o" should be
> allowed to bypass this check, otherwise by default they should go through the
> check.
>
> It is important to keep "unset of the procedure from RegionStateNode" and
> "bypassing preTransitCheck" separate so that when the cluster state is bad,
> we don't explicitly deteriorate it further e.g. if a region was successfully
> split and now if operator performs "hbck assigns \{region} -o" and if it
> bypasses the transit check, master would bring the region online and it could
> compact store files and archive the store file which is referenced by
> daughter region. This would not allow daughter region to come online.
> Let's introduce hbase site config to allow bypassing preTransitCheck, it
> should not be doable only by operator using hbck alone.
>
> "-o" should mean "override" the procedure that is attached to the
> RegionStateNode, it should not mean forcefully skip any region transition
> validation checks.
