Hey all, I am trying to run spark-submit on a Jar file without specifying the --class parameter so that it will load the jar's main class. Using the following command:
spark-submit MyJar.jar I get this error: Error: Cannot load main class from JAR: file:/MyJar.jar After digging into the issue, it seems that the problem occurs on this line: https://github.com/apache/spark/blob/2f54543815c0905dc958d444ad638c23a29507c6/core/src/main/scala/org/apache/spark/deploy/SparkSubmitArguments.scala#L127 The JarFile constructor does not like the "file:/" that was prepended to the file name. I tried opening up the scala console and trying it out myself and confirmed that 'new JarFile("file:/MyJar.jar")' does throw a FileNotFoundException, while 'new JarFile("MyJar.jar")' works as expected. Has anyone encountered this issue or know of a way around it? I would like to avoid specifying the --class parameter if possible.
