> The client path is /data/home/spark/test/spark-1.0.0 while the worker deploy path is /data/home/spark/spark-1.0.0 which is different from the client path. Then an application is launched using the ./bin/spark-submit --class JobTaskJoin --master spark://172.25.38.244:7077 --executor-memory 128M ../jobtaskjoin_2.10-1.0.0.jar. However the application is failed because an exception occurs at

> Therefore, I think worker should not use appDesc.sparkHome when LaunchExecutor, Contrarily, worker could use its own sparkHome directly.
