Spark job using HBase fails

Any Spark job I run that involves HBase access results in the errors below. My own jobs are in Scala, but supplied python examples end the same. The cluster is Cloudera, running CDH 5.4.4. The same jobs run fine on a different cluster with CDH 5.3.1.

Any help is greatly apreciated!

run spark-shell with this parameters: --driver-class-path .../cloudera/parcels/CDH/lib/hbase/lib/htrace-core-3.1.0-incubating.jar --driver-java-options "-Dspark.executor.extraClassPath=.../cloudera/parcels/CDH/lib/hbase/lib/htrace-core-3.1.0-incubating.jar"

Why it works is described here.
