------------------------------------------
Summary: Save replication znodes while migrating to 0.96
Key: HBASE-9141
URL: https://issues.apache.org/jira/browse/HBASE-9141
Project: HBase
Issue Type: Improvement
Components: migration, Replication
Affects Versions: 0.94.10
Reporter: Himanshu Vashishtha
Fix For: 0.95.2
While migrating to 0.96, we recommend deleting old znodes so users not face
issues like HBASE-7766, and let HBase create them out of box.
Though HBase tends to store only ephemeral data in zookeeper, replication has a
different approach. Almost all of its data (state, peer info, logs, etc) is
present in zookeeper. We would like to preserve them in order to not do
re-adding of peers, and ensuring complete replication after we have migrated to
0.96.
This jira adds a tool to serialize/de-serialize replication znodes to the
underlying filesystem. This could be used while migrating to 0.96.0.
