Hi there, When reading Spark on YARN code, I have one question regarding prepareCommand in WorkerRunnableUtil: This function is used to build command to run in executor, why doesn't it follow the same way as ExectorRunner(Standalone mode) where the "run" script is used to run the command? Is there any special consideration to choose a different way? The reason I ask this question is we have already put some stuff in the run script such as classpath, if we can use the same way, we can just use the same script. Thanks.
