Hi, I tried to run a test case using this command from my Linux box: mvn clean test -PtestKerberos -Dtest=TestJHSSecurity
And I got the following exception. I know it is related to setup the principal and other kerberos settings. Can someone please help me about this? such as what is the mvn command and what other settings are required? Do I need to run my own KDC or provide own keytab?
