apache-spark - Livy REST Spark java.io.FileNotFoundException:

Question

我是BigData的新手，我曾尝试用apache Livy调用spark作业。
与提交命令行工作正常。有天赋的我有异常(exception)

命令行:

curl -X POST --data '{"file": "/user/romain/spark-examples.jar", "className": "org.apache.spark.examples.SparkPi"}' -H 'Content-Type: application/json' http://localhost:8998/batches

Livy日志:

与@ cricket_007注释有关，由execute hadoop fs -copyFromLocal命令行解决
