Hello all, Currently sentry doesn’t have solution to backup the sentry permission information and restore them in the same OR new cluster. This capability would help in solving disaster recovery and also replication use cases. This means that Sentry should be able to replicate the permission information and also update the HDFS ACLs in the target cluster in both active-passive and dual-active production environments and be performant at multi-petabyte data scale.
I'm looking into this feature and have a design in place. I would like the community to look at it and let me know what you think. Here is the link for the doc. <https://docs.google.com/document/d/1ZnNpoc-0v4iso6c5hhB450nw_7mvEx66VDc37k6P1Vo/edit?usp=sharing> -Kalyan
