Subject Re: Migrate ZK to ACL ZK
Date Sat, 19 Jan 2019 19:25:12 GMT
Hi Ryan,
I think this should be supported by NiFi, but I don't know that platform.

Username/password is very weak and it is hard to maintain.

Apart from this I think you can write a simple program which scans your ZK
tree and applies ACL, no need for a new cluster.

Just my 2 cents
