> Replication Znodes Backup Tool
> ------------------------------
>
> 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
> Assignee: Himanshu Vashishtha
> Fix For: 0.95.2
>
> Attachments: HBase-9141.patch
>
>
> 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.
