[jira] [Created] (HDDS-1371) Download RocksDB checkpoint from OM
Leader to Follower
Hanisha Koneru created HDDS-1371:
------------------------------------
Summary: 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
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 servlet used by Recon server.
