Error Connecting to an existing spark cluster

[alu...@gmail.com]

Hi,
It was wonderful to play around with different examples in the Spark Notebook in the standalone version.
However, when I try to connect to an Cloudera based existing Spark cluster, i'm facing some class version issues. So I tried to override that to use my version of jars by settting the CLASSPATH_OVERRIDES in the script "bin/spark-notebook". However that results in a different error while starting the notebook. Any ideas what could be wrong here?

Regards
Al
