A Big Data Job fails with the following Kerberos exception:
java.lang.IllegalArgumentException: Server has invalid Kerberos principal
The configuration or server details are not correct.
Ensure that all of these values in the context and krb5.conf/ini files are correct. Run kinit and verify that the domain and user are correct.
In this case, the context file had three equal (=) signs instead of two as they were using in the implicit context file. After this was fixed, the Job ran successfully.
