[jira] [Commented] (KUDU-2070) Improve documentation/error when
submitting secure spark jobs without specifying keytab/principal
[ https://issues.apache.org/jira/browse/KUDU-2070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16102682#comment-16102682 ]
Todd Lipcon commented on KUDU-2070:
-----------------------------------
Is this bad error message specific to spark submission? Or do we get the same thing any time we attempt to use the Java client against a secure cluster with no Kerberos credentials? I would have thought the latter.

> When submitting spark2 jobs in cluster deploy-mode against a secure Kudu instance, it's always necessary to specify {{\--keytab}} and {{\--principal}} flags. We should document this better, and if possible, improve the error messages to suggest setting these flags. The specific error that omitting these flags causes is:
