There might be the possible below cause.   1. If the script is running fine manually from your user, then maybe a problem with the binary path.  Export the kinit binary path in the script.   export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/latest/bin:/usr/java/latest/jre/bin:/root/bin:/bin"   2. check the permission for the key tab file and the RWX permission for the user 3. If the above solution not works try to add the ticket generation command separately in corn  for every 10 min and test the script. */10 * * * * kinit -kt /root/user.keytab user@PROD.EDH     ...

Hello, By following the link shared by Umain, I have been able to install on my home laptop(Mac), because it install different images(sandbox-hdp & sandbox-proxy).

First of all doublecheck all configurations (incl. password). Just to avoid moving in the right direction. Secondly confirm that you do not need TLS enabled. If these don't help, the following might help with troubleshooting: 1. Become nifi on the node where nifi is running 2. Send the message via Python 3. Share the python command here Note: Please explicity specify all things that you configure in nify when executing python (even if they are not needed because of good defaults for instance). ...

Have a look at this if you need to by pass Avro for Hive DDL: https://github.com/tspannhw/nifi-convertjsontoddl-processor If you need to convert JSON to ORC (for Hive) Avro will be required. You will need to write/manage Avro schemas (recommended will be to use Schema Registry for that). Alternatively you can use Infer Avro schema to detect incoming schema from JSON but it may not be 100% correct all the time. ... View more

Usually by default the ticket expires 24 hours and cache expires 7 days. Depends on your directory services policies. Within 7 days you can do kinit -R for users. klist will show ticket and cache expiry time. Or you can use keytabs to automate ticket renewal. You don't have to kinit for hadoop services (ever), ticket renewal is managed automatically. ... View more
