The problem is that we force the user to add "Principal=xxxx" to the URL in the Server Properties when using Kerberos. For the Simba drivers, this looks like it has changed from Apache. There is nothing in the Simba docs that indicates that you can use the Principal parameter where the Cloudera Impala docs using Apache say that you have too. Examples of both...

 

Impala with Apache - > jdbc:hive2://myhost.example.com:21050/;principal=impala/myhost.example.com@H2.EXAMPLE.COM

 

Impala with Simba - > jdbc:impala://localhost:21050;AuthMech=1;KrbRealm=EXAMPLE.COM;Krb HostFQDN=impala.example.com;KrbServiceName=impala 

 

 

As proof.. This URL works for the customer.              String url = "jdbc:impala://nyrmpla527.ny.fw.gs.com:21050;AuthMech=1;" +

 

Unfortunately, we make the user fill in the Principal field in the Server Properties and that is added to the URL. A change is needed that removes the Principal field check and doesn't add principal to the URL when the Simba drivers are loaded. This can be tested and if it works perhaps a more permanent change can be added specifically for the Simba drivers.
