Assignee: Peter Lee
> SCM should not close QUASI_CLOSED containers on majority quorum
> ---------------------------------------------------------------
>
> Key: HDDS-12237
> URL: https://issues.apache.org/jira/browse/HDDS-12237
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Swaminathan Balachandran
> Assignee: Peter Lee
> Priority: Major
>
> When there are 2 replicas belonging to different origin id(2 different origin
> datanodeIds where the data was first created) in QUASI_CLOSED state. SCM
> assumes that there is majority quorum and ends up closing the container with
> a higher bcsid(both if they are equal). This is wrong since this would be
> only true if the transactions have been applied to 2 datanodes but ratis only
> guarantees the transaction would be committed to one of the follower raft log
> and applied on leader. There is no guarantee for follower apply transactions.
> SCM should close QUASI_CLOSED containers only when all replicas belonging to
> different origin id are present and not just the majority of the replicas. It
> can also close a QUASI_CLOSED container when there is a CLOSED container
> replica reported and the bcsid of the QUASI_CLOSED container matches the
> CLOSED container.
