Aravindan Vijayan updated HDDS-2848:
------------------------------------
Summary: Recon should work with OM HA (was: Verify Recon works as expected
with OM HA)
> Recon should work with OM HA
> ----------------------------
>
> Key: HDDS-2848
> URL: https://issues.apache.org/jira/browse/HDDS-2848
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: Ozone Recon
> Reporter: Aravindan Vijayan
> Priority: Major
>
> Since Recon already uses the OzoneManagerClientProtocol to query the
> OzoneManager, on an OM HAcluster, the RPC client automatically routes the
> request to the leader. Recon only needs the updates from the OM RocksDB
> store, and does not need the in flight updates in the OM DoubleBuffer. Due to
> the guarantee from Ratis that the leader’s RocksDB will always be up to date,
> Recon does not need to worry about going back in time when a current OM
> leader goes down. In this version of Recon, the plan is to test out OM HA
> scenarios and add unit/integration tests to verify correct behavior
