Github user iven commented on the pull request: https://github.com/apache/spark/pull/1969#issuecomment-52388625 @JoshRosen I'm using Spark 1.0.1 with Mesos. If I don't specify SPARK_HOME in the driver, Mesos executors will LOST with error: ``` sh: /root/spark_master/sbin/spark-executor: No such file or directory ``` Where `/root/spark_master` is the `SPARK_HOME` of the driver. I think this is caused by `createExecutorInfo` method in `MesosSchedulerBackend.scala`. When `spark.executor.uri` is not specified, it will use `SPARK_HOME` from `SparkContext`.
