Apache Spark 运行 spark-shell 出现 YARN 错误
Apache Spark running spark-shell on YARN error
我从 http://spark.apache.org/downloads.html 下载了：spark-2.1.0-bin-hadoop2.7.tgz。我的 Hadoop HDFS 和 YARN 以 $ start-dfs.sh 和 $ start-yarn.sh 开头。但是 运行 $ spark-shell --master yarn --deploy-mode client 给我以下错误：
$ spark-shell --master yarn --deploy-mode client
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

YARN 检测到 Spark 是 运行 它，但错误导致 Spark 以未定义状态退出。
我从另一个 Whosebug 问题中找到了解决方案。这不是关于配置 Apache Spark，而是关于配置 Hadoop YARN：
Running yarn with spark not working with Java 8
确保您的 Hadoop 配置文件夹中的 yarn-site.xml 具有以下属性：
<property>
<name>yarn.nodemanager.pmem-check-enabled</name>
<value>false</value>
</property>
<property>
<name>yarn.nodemanager.vmem-check-enabled</name>
<value>false</value>
</property>
我遇到了和你一样的问题。当我检查 NodeManager 日志时，我发现这个警告：
2017-10-26 19:43:21,787 WARN org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainersMonitorImpl: Container [pid=3820,containerID=container_1509016963775_0001_02_000001] is running beyond virtual memory limits. Current usage: 339.0 MB of 1 GB physical memory used; 2.2 GB of 2.1 GB virtual memory used. Killing container.
所以我设置了更大的虚拟内存（yarn.nodemanager.vmem-pmem-ratio in yarn-site.xml，默认值为2.1）。然后果然有效
我从 http://spark.apache.org/downloads.html 下载了：spark-2.1.0-bin-hadoop2.7.tgz。我的 Hadoop HDFS 和 YARN 以 $ start-dfs.sh 和 $ start-yarn.sh 开头。但是 运行 $ spark-shell --master yarn --deploy-mode client 给我以下错误：
