> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Hanisha Koneru

> If a follower OM is lagging way behind the leader OM or in case of a restart or bootstrapping, a follower OM might need RocksDB checkpoint from the leader to catch up with it. This is because the leader might have purged its logs after taking a snapshot.
> This Jira aims to add support to download a RocksDB checkpoint from leader OM to follower OM through a HTTP servlet. We reuse the DBCheckpoint servlet used by Recon server.
