报错org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /user/root/.sparkStaging/applicat

初学spark时运行

bin/spark-submit --class org.apache.spark.examples.SparkPi --master yarn --deploy-mode client ./examples/jars/spark-examples_2.12-3.0.0.jar 10

报错

解决方法

发现自己用的spark3.0.0依赖hadoop3.2

重装hadoop完美运行
