Description

This seems to have regressed in Run ID : 61142, but was working fine in Run ID : 60868 (which was Thursday night run). Livy for Spark2 is failing to impersonate users

after I setup hadoop.proxyusers.livy.hosts=* and hadoop.proxyusers.livy.groups=* in core-site
it gives following error which is expected because of some other test failures on this cluster
java.lang.IllegalArgumentException: Unable to instantiate SparkSession with LLAP support because LLAP or Hive classes are not found.
