启动Spark有时成功有时报错

环境：spark-2.4.8+CDH-6.3.2+scala-1.11.12

报错信息：

Application application_1669708409043_0014 failed 2 times due to AM Container for appattempt_1669708409043_0014_000002 exited with exitCode: 1Failing this attempt.Diagnostics: [2022-11-29 18:01:11.661]Exception from container-launch.Container id: container_1669708409043_0014_02_000001Exit code: 1[2022-11-29 18:01:11.663]Container exited with a non-zero exit code 1.

原因：路径jar包没有识别读取到

解决办法：spark配置文件&#f 中的spark.yarn.jars=路径找不到，检查hdfs或本地路径是否正确。注意：路径结尾加*。
