> Download RocksDB checkpoint from OM Leader to Follower
> ------------------------------------------------------

> Key: HDDS-1371
> URL: https://issues.apache.org/jira/browse/HDDS-1371
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Reporter: Hanisha Koneru
> Assignee: Hanisha Koneru
> Priority: Major
> Labels: pull-request-available
> Fix For: 0.5.0
>
> Time Spent: 8h
> Remaining Estimate: 0h
>
> 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.
