Satish Duggana commented on KAFKA-7694:
---------------------------------------
This is about giving pluggable interfaces for delegation token storage and
master key management and have zookeeper storage as the default implementation.
I am working on a KIP for the above, I will send it out when it is ready.

>
> Master/secret key is used to generate and verify delegation tokens.
> currently, master key/secret is stored as plain text in server.properties
> config file. Same key must be configured across all the brokers. We require a
> re-deployment when the secret needs to be rotated.
> This JIRA is to explore and implement a ZooKeeper based master/secret key
> management to automate secret key generation and expiration.
