Question

我的火花作业由oozie在色调中提交。火花以纱线簇模式运行。我试图通过所谓的驱动程序4040端口监视正在运行的应用程序状态，但是我找不到4040端口，我检查过程：

appuser 137872 137870 0 18:55 ? 00:00:00 /bin/bash -c /home/jdk/bin/java -server -Xmx4096m -Djava.io.tmpdir=/data6/data/hadoop/tmp/usercache/appuser/appcache/application_1493800575189_0547/container_1493800575189_0547_01_000004/tmp '-Dspark.driver.port=36503' '-Dspark.ui.port=0' -Dspark.yarn.app.container.log.dir=/home/log/hadoop/logs/userlogs/application_1493800575189_0547/container_1493800575189_0547_01_000004 -XX:OnOutOfMemoryError='kill %p' org.apache.spark.executor.CoarseGrainedExecutorBackend --driver-url spark://CoarseGrainedScheduler@10.120.117.107:36503 --executor-id 3 --hostname 10.120.117.100 --cores 1 --app-id application_1493800575189_0547 --user-class-path file:/data6/data/hadoop/tmp/usercache/appuser/appcache/application_1493800575189_0547/container_1493800575189_0547_01_000004/__app__.jar 1> /home/log/hadoop/logs/userlogs/application_1493800575189_0547/container_1493800575189_0547_01_000004/stdout 2> /home/log/hadoop/logs/userlogs/application_1493800575189_0547/container_1493800575189_0547_01_000004/stderr

我不知道为什么spark.ui.port是0而不是4040.当然，我的linux系统不允许端口0。所以，我无法从REST api监视应用程序状态。< / p>

有人可以给我一些建议吗？

非常感谢Mariusz的回答，下面是一个火花的ApplicationMaster流程吗？

[appuser@hz-10-120-117-100 bin]$ ps -ef|grep ApplicationMaster

根据Spark的官方文档，驱动程序应该有一个4040端口用于监控，但我的驱动程序似乎没有打开任何端口：

[appuser@hz-10-120-117-100 bin]$ netstat -ntlp|grep 125805
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

我最终找到驱动程序端口的目的是监视应用程序状态。有什么建议吗？

Answer 1

您列出的流程是执行人，而不是驱动程序。

在yarn-cluster模式下运行应用程序时，spark driver和yarn application master在同一个JVM中运行。因此，确定Spark UI地址的最简单方法是转到经理的UI，找到您的应用程序并单击指向Application Master的链接。这将是一个代理地址，指向驱动程序的ui端口。

如何找到我的Spark的驱动程序节点？
