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.yarnweb界面查看运行log
