> Storm Nimbus Hook
> -----------------

> Key: STORM-1098
> URL: https://issues.apache.org/jira/browse/STORM-1098
> Project: Apache Storm
> Issue Type: New Feature
> Components: storm-core
> Reporter: Sriharsha Chintalapani
> Assignee: Parth Brahmbhatt
>
> Apache Atlas provides governance services and also lineage. It will be great
> if we can capture the topology changes as part of Apache Atlas so that user
> can see how the topology changed over the period of time.
> Storm has ITaskHook but this is for topology components like spout & bolt.
> Similar to ITaskHook we should provide a nimbus hook that will allow
> pluggable implementations to run and can nimbus will execute this on any
> topology operation like upload jar, download, activate, deactivate , kill
> etc..
