[jira] [Commented] (SPARK-26522) Auth secret error in RBackendAuthHandler

["Hyukjin Kwon (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-26522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16732762#comment-16732762 ] 

Hyukjin Kwon commented on SPARK-26522:
--------------------------------------

I think it's something Livy should support rather than letting Spark support insecure connection.
See also SPARK-26019. I don't think it's going to be at the very least fixed in Spark 3.0.

WDYT [~vanzin] and [~irashid]?
