sparkdemo.jar运行在yarn上的过程是什么-编程学习网

sparkdemo.jar运行在yarn上的过程是什么，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。

1.将之前打包的jar包上传
[root@sht-sgmhadoopnn-01 spark]# pwd
/root/learnproject/app/spark
[root@sht-sgmhadoopnn-01 spark]# rz

2.以下是错误

1 ERROR1: Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
IDEA打包的jar包,需要使用zip删除指定文件
zip -d sparkdemo.jar META-INF/*.RSA META-INF/*.DSA META-INF/*.SF

2 ERROR2: Exception in thread "main" java.lang.UnsupportedClassVersionError: com/learn/java/main/OnLineLogAnalysis2 : Unsupported major.minor version 52.0
yarn环境的jdk版本低于编译jar包的jdk版本(需要一致或者高于;每个节点需要安装jdk,同时修改每个节点的hadoop-env.sh文件的JAVA_HOME参数指向)

3 ERROR3: java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()Lcom/google/common/base/Stopwatch;

抛错信息为NoSuchMethodError，表示 guava可能有多版本，则低版本

[root@sht-sgmhadoopnn-01 app]#
[root@sht-sgmhadoopnn-01 app]# find ./ -name *guava*
[root@sht-sgmhadoopnn-01 app]# mv ./hadoop/share/hadoop/yarn/lib/guava-11.0.2.jar ./hadoop/share/hadoop/yarn/lib/guava-11.0.2.jar.bak
[root@sht-sgmhadoopnn-01 app]# cp ./spark/libs/guava-20.0.jar ./hadoop/share/hadoop/yarn/lib/

[root@sht-sgmhadoopnn-01 app]# mv ./spark/jars/guava-14.0.1.jar ./spark/jars/guava-14.0.1.jar.bak
[root@sht-sgmhadoopnn-01 app]# cp ./spark/libs/guava-20.0.jar ./spark/jars/

[root@sht-sgmhadoopnn-01 app]# cp ./spark/libs/guava-20.0.jar ./hadoop/share/hadoop/common/lib/

3.后台提交jar包运行
[root@sht-sgmhadoopnn-01 spark]#
[root@sht-sgmhadoopnn-01 spark]# nohup /root/learnproject/app/spark/bin/spark-submit \
> --name onlineLogsAnalysis \
> --master yarn    \
> --deploy-mode cluster     \
> --conf "spark.scheduler.mode=FAIR" \
> --conf "spark.sql.codegen=true" \
> --driver-memory 2G \
> --executor-memory 2G \
> --executor-cores 1 \
> --num-executors 3 \
> --class com.learn.java.main.OnLineLogAnalysis2     \
> /root/learnproject/app/spark/sparkdemo.jar &
[1] 22926
[root@sht-sgmhadoopnn-01 spark]# nohup: ignoring input and appending output to `nohup.out'

[root@sht-sgmhadoopnn-01 spark]#
[root@sht-sgmhadoopnn-01 spark]#
[root@sht-sgmhadoopnn-01 spark]# tail -f nohup.out

4.yarn web界面查看运行log
sparkdemo.jar运行在yarn上的过程是什么

ApplicationMaster：打开为spark history server web界面
logs：查看stderr 和 stdout日志 (system.out.println方法输出到stdout日志中)

5.查看spark history web

6.查看DashBoard ,实时可视化
