Hello, As kafka from HDP 3.0 is moving to HDF, i would like to know how we can move HDP kafka to HDF. I could not found a solution or use cases online that have already implemented this. Can anyone please provide details of what needs to be done to move kafka to hdf. We are using HDP 2.5 and already have HDF cluster where nifi is running with 3 zookeeper nodes.

Make sure that the client is configured to use a ticket cache (using the JAAS configuration setting 'useTicketCache=true)' and restart the client. If you still get this message after that, the TGT in the ticket cache has expired and must be manually refreshed. To do so, first determine if you are using a password or a keytab. If the former, run kinit in a Unix shell in the environment of the user who is running this Zookeeper client using the command 'kinit ' (where is the name of the client's Kerberos principal). If the latter, do 'kinit -k -t ' (where is the name of the Kerberos principal, and is the location of the keytab file). After manually refreshing your cache, restart this client. If you continue to see this message after manually refreshing your cache, ensure that your KDC host's clock is in sync with this host's clock.
