Subject Is there a difference between --proxy-user or HADOOP_USER_NAME in a non-Kerberized YARN cluster?
Date Thu, 16 May 2019 17:49:02 GMT
Let's suppose we're dealing with a non-secured (i.e. not Kerberized)
YARN cluster.  When I invoke spark-submit, is there a practical
difference between specifying --proxy-user=foo (supposing
impersonation is properly set up) or setting the environment variable
HADOOP_USER_NAME=foo?  Thanks for any insights or links to docs.
