> ZooKeeper migration toolkit
> ---------------------------
>
> Key: NIFI-2957
> URL: https://issues.apache.org/jira/browse/NIFI-2957
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Tools and Build
> Affects Versions: 1.0.0, 0.7.1
> Reporter: Jeff Storck
> Assignee: Jeff Storck
> Fix For: 1.2.0
>
>
> When upgrading from NiFi 0.x to 1.x, or when it is desired to move from the
> embedded ZooKeeper to an external ZooKeeper, state from ZooKeeper needs to be
> migrated.
> Initial considerations:
> * Username/password protection of nodes is not supported in NiFi 1.x.. Those
> nodes that are configured that way in ZooKeeper need to be migrated to have
> an open ACL.
> * The toolkit will support a mode to read data from a configurable root node
> in a source ZooKeeper, and the data will be written to a file designated via
> CLI.
> * The toolkit will support a mode to write data to a destination ZooKeeper
> * The toolkit will not allow data to be written to the same ZooKeeper from
> which the source data was obtained.
> * The toolkit will not support reconnecting to ZooKeeper if it is
> disconnected. The user can rerun the tool.
> * The toolkit will support ZooKeepers configured with Kerberos.
