I'm starting a spark shell on a MapR 5.2.0 client with Spark 2.1.0 and I'm getting some strange errors I haven't seen on other versions.

java.lang.ClassNotFoundException: org.apache.hadoop.yarn.server.webproxy.amfilter.AmIpFilter

... (lots of similar garbage)

Caused by: javax.servlet.UnavailableException: org.apache.hadoop.yarn.server.webproxy.amfilter.AmIpFilter

The spark context and spark session start up correctly and spark is usable without any obvious issues.  Any idea what this is and how to get rid of it?
