Summary: Utility to automate upgrade/downgrade of NiFi
Key: NIFI-3663
URL: https://issues.apache.org/jira/browse/NIFI-3663
Project: Apache NiFi
Issue Type: New Feature
Components: Tools and Build
Reporter: Yolanda M. Davis
Assignee: Yolanda M. Davis
Upgrading NiFi either in standalone mode or within a cluster currently requires
several manual steps to ensure that an existing NiFi node is properly migrated
to a new version. Also there is no support for "rolling upgrade" which would
allow upgrade of a NiFi cluster to occur without a full outage of the cluster.
This limits a clusters ability to provide a highly available environment for
flow execution and also requires more coordination to plan and schedule for
full outages.
Having a utility (or a set of utilities) that can support a more seamless move
to a new version of NiFi (either in rolling or non-rolling fashion) would help
to further support automation of configuration and management for NiFi. Such a
utility could also be leveraged by more enterprise level configuration
management frameworks (e.g. Ansible, Puppet, Chef, Salt) to coordinate upgrades
across multiple nodes or clusters within an environment.
