Uma Maheswara Rao G updated HDDS-12305:
---------------------------------------
Summary: Avoid marking container as DELETED if it was due to EMPTY with
BCSID=0 containers (was: Avoid marking container as DELETED if it was due to
deletion of BCSID=0 containers)
> Avoid marking container as DELETED if it was due to EMPTY with BCSID=0

> Key: HDDS-12305
> URL: https://issues.apache.org/jira/browse/HDDS-12305
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Uma Maheswara Rao G
> Priority: Major
>
> BCSID=0 means, there might be some errors in apply transaction. When first
> writing chunk only we will create containers. By default, BCSID will be 0. As
> applyTransactions played, this BCSID will keep getting incremented. A
> container being reported with BCSID=0 means, either node failed right after
> creating the container or failed to apply the transaction.
> It may be a safe check to make SCM not to mark the whole container as DELETED
> based on EMPTY BSCID=0 container reports from SCMs. Instead, we can just
> delete only that specific replica.
> In one of the offline discussions, @Tsz Sze brought up this point. Not to
> lose track of this point, log the Jira here. Let's discuss if there are other
> cases to take care of it.
