Hanisha Koneru updated HDDS-1371:
---------------------------------
Description:
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.
