Thank you very much Yana for replying! So right now the set up is a single-node machine which is my "cluster", and YES you are right my submitting laptop has a different path to the spark-1.0.0 installation than the "cluster" machine.
I tried to set SPARK_HOME on my submittor laptop using the actual path of the CLUSTER's directories...hoping this would help. It didn't change anything. Let me show you the command from the submission side on my laptop - keep in mind I set SPARK_HOME as the path for the cluster. SPARK_HOME=/home/data/Documents/spark-1.0.0/ ~/Documents/spark-1.0.0/bin/spark-submit --verbose --class org.apache.spark.examples.SparkPi --master spark://10.20.10.152:7077 ~/Documents/spark-1.0.0/examples/target/scala-2.10/spark-examples-1.0.0-hadoop1.0.4.jar I get the same problems as originally. I am actually confused here - if I set the SPARK_HOME on the same line as the spark-submit command, I don't get how the submittor script did not get all confused just running bin/spark-submit...but what do I know. Am I setting SPARK_HOME correctly?
