> Key: HBASE-20835
> URL: https://issues.apache.org/jira/browse/HBASE-20835
> Project: HBase
> Issue Type: Task
> Components: Replication
> Affects Versions: 2.1.0
> Reporter: Mike Drob
> Assignee: Duo Zhang
> Priority: Critical
>
> Based on my questions at the tail end of HBASE-19543
> bq. We have some tooling that checks on replication queues and reads the
> znode as the source of truth. When replication is disabled, it's expected
> that the node was still there, but just empty. Is there a better way to get
> this same information?
> I understand that with table based replication it doesn't make sense to check
> ZK for status. However, losing the ability to inspect the data and get
> information is a tough hit for operators. Do we have APIs that expose the
> same sort of metrics?
> bq. how many peers/queues, queue size, position in the queue, and age of last
> op
> Assigning to you for now, Duo, since you were both primary implementor and RM
> for 2.1.0 and I'm not sure who else would know the answers. If the docs
> already exist, then nothing to do but we should include them in the RN. Maybe
> this will need additional code, but I hope it's already there and is
> something we can write a workaround for.
