Question

Mesosphere在简化在Mesos上运行Spark的过程方面做得很好。我正在使用本指南在Google Cloud Compute上设置开发Mesos群集。

https://mesosphere.com/docs/tutorials/run-spark-on-mesos/

我可以使用spark-shell（查找小于10的数字）运行指南中的示例。但是，当我尝试提交一个本地可以正常使用Spark的应用程序时，会出现TASK_FAILED消息（即CoarseMesosSchedulerBackend: Mesos task 4 is now TASK_FAILED）。

这是我使用提供的Spark Pi示例的命令。

./spark-submit --class org.apache.spark.examples.SparkPi --master mesos://10.173.40.36:5050 ~/spark-1.3.0-bin-hadoop2.4/lib/spark-examples-1.3.0-hadoop2.4.0.jar 100

输出：

jclouds@development-5159-d9:~/learning-spark$ ~/spark-1.3.0-bin-hadoop2.4/bin/spark-submit --class org.apache.spark.examples.SparkPi --master mesos://10.173.40.36:5050 ~/spark-1.3.0-bin-hadoop2.4/lib/spark-examples-1.3.0-hadoop2.4.0.jar 100

我怀疑它可能与 mesos slave节点没有找到应用程序jar 有关，但当我把它放在HDFS并提供URL时，spark-submit告诉我它会Skip remote jar。

编辑：只是为了得出结论，火花用户列表上的hbogert指向我调试我的一个从节点上的spark日志的方向，问题就像白天一样清晰

无法在Mesos群集上使用应用程序jar运行spark-submit
