I think we have to copy this to a location on HDFS, /sparkjars/ seems a good a directory to create as any. I think the file has to be world readable 2. Set the spark_jar_hdfs_path property in Cloudera Manager e.g. hdfs:///sparkjars It still doesn't seem to work can someone please help me with this.
