---------------------------------
Summary: Document how to get replication reporting
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
Fix For: 2.1.0
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.
