@Ian Roberts I believe we can do something like this: For example if you are running spark shell then you can add below configurations in core-site.xml and run your job with --proxy-user <username> <property>
<name>hadoop.proxyuser.<username>.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.<username>.groups</name>
<value>*</value>
</property>
Command to run spark shell with YARN with proxy user:
spark-shell --master yarn-client --proxy-user <username>
