GSS initiate failed exception simply means that the provided credentials are incorrect.

You must have kerberised the cluster with a principal/keytab combination. Please provide that as the kerberos principa;/keytab. The credentials that you have provided are that of the hive service.

Re: NiFi Hive Connection Pool Error.

Could you also add core-site.xml in Hive Configuration Properties from your kerberosed cluster please?

I was having the same issue but after I added core-site.xml alongside my hive-site.xml file I was able to connect. Thanks!

/usr/hdp/current/hive/conf/hive-site.xml,/etc/hadoop/current/0/core-site.xml

@mkalyanpur do I have to copy the krb5.conf file from my Hive server to the NiFi server?
