Hi Is there anyone who is in the same scenario and manage to use nifi executesql with impala driver to query kerberos kudu successfully?
I have tried many of cloudera Impala's drivers and the one that is working with a non-kerberos environment is Impala JDBC Connector 2.6.4. The other versions display error: "com.cloudera.impala.jdbc41.internal.apache.thrift.transport.Tsocket"
For the kerberos kudu, I used Impala JDBC Connector 2.6.4 and tried with KerberosCredentialService but failed with error: "Privileged action failed due to: null"
Then i tried removing KerberosCredentialService and used the following URL but failed with error as well: "Error creating login context using ticket cache: Unable to obtain Principal Name for authentication"
