Hello After upgrading from datahub v0.8.45 to 0.9.3 the mae and mce are unable to communicate with kerberised kafka broker. Same settings work fine if i switch back to v0.8.45. Is it because datahub v0.9.3 has upgraded to openjdk11 which does not support legacy KRB5-based cipher suites. If yes how can i mitigate this ? Exception:

Please let us know how this worked out

Does not work. Still getting the same error. If i use jdk8 instead of 11 will i face any issues. I can see a lot of code was converted to jdk11 https://github.com/datahub-project/datahub/pull/5836/files

0.9.0 we migrated the codebase from jdk8 to jdk11

that's why 0.8.45 works fine.

Does not work. Still getting the same error.

How did you try this? Did you comment out the line as suggested? And build container with that file?

Yes

🙌 @rich-policeman-92383 thanks for getting back with the solution.
