Hi @ sangameshwar swami, Which version are you upgrading from? Did you follow the recommendations from previous answers in terms of upgrade sequence of the services? I performed an upgrade from 3.0.1.1 to the latest 3.1.1 a week ago and had no major issues. Regards, Geouffrey ... View more

Any idea if there are any plans to include the kafka rest proxy in the near future into HDF. I noticed the JIRA has been closed as it didn't pass community vote but it's been added to the confluent platform and was wondering if the same will occur for HDF ... View more

@Raffaele S, That is a bummer, I feel your pain. I had a similar scenario a few months ago trying to upgrade to HDF 3 and ended up reinstalling and configuring an entire cluster. Hope it goes better with the next upgrade. ... View more

Hey @Raffaele S, Unfortunately not. In the end I reverted to backups to HDF 3.0.1 and performed an upgrade to 3.0.1.1 instead, which is using Ambari 2.5.1.

I've confirmed the versions of my server and all agents are the same but is there perhaps something else I might've missed? Regards, Geouffrey ... View more
