> 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
> 17/08/28 17:45:55 INFO ContextLauncher: ERROR:
> org.apache.hadoop.security.authorize.AuthorizationException: User: livy is
> not allowed to impersonate hrt_1
> 17/08/28 17:45:55 WARN ContextLauncher: Child process exited with code 1.
> 17/08/28 17:45:55 ERROR RSCClient: Failed to connect to context.

> at java.lang.Thread.run(Thread.java:748)
> 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.
