@srowen Currently, when you do `run-example`, `SparkSubmitCommandBuilder` will auto add `--jars` (set to all jars in `examples/jars` folder) for you. https://github.com/apache/spark/blob/f5360e761ef161f7e04526b59a4baf53f1cf8cd5/launcher/src/main/java/org/apache/spark/launcher/SparkSubmitCommandBuilder.java#L215-L217 However, `--jars` is different from `<application-jar>` (aka primaryResource, which contains your Main-Class) . So when it (in standalone cluster mode) goes to: https://github.com/apache/spark/blob/32d87c2b595b4aac2d9274424a43697299638f61/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L695-L696 https://github.com/apache/spark/blob/f55694638d45f34ab91f6f6ec2066cbf7631f4af/core/src/main/scala/org/apache/spark/deploy/ClientArguments.scala#L74-L89 We get the error described in [SPARK-32804]: 1. Missing primaryResource arg. ====> aka `<application-jar>` 2. Wrong appResource arg. ====> "spark-internal" should not be set as an arg in `run-example` Actually, in [SPARK-32804], "spark-internal" is treated as primaryResource  (But client mode does not have the problem.) I would say it's kind of tricky...... ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
