Question

我有一个安装了spark的docker容器，我正在尝试使用marathon将作业提交给其他群集上的yarn。 docker容器具有yarn和hadoop conf dir的导出值，yarn文件还包含emr master ip的正确地址，但是我不确定它从哪里作为本地主机？

ENV YARN_CONF_DIR="/opt/yarn-site.xml"
ENV HADOOP_CONF_DIR="/opt/spark-2.2.0-bin-hadoop2.6"

Yarn.xml

<property>
    <name>yarn.resourcemanager.hostname</name>
    <value>xx.xxx.x.xx</value>
  </property>

命令：

  "cmd": "/opt/spark-2.2.0-bin-hadoop2.6/bin/spark-submit --verbose \\\n --name emr_external_mpv_streaming \\\n --deploy-mode client \\\n --master yarn\\\n --conf spark.executor.instances=4 \\\n --conf spark.executor.cores=1 \\\n --conf spark.executor.memory=1g \\\n --conf spark.driver.memory=1g \\\n --conf spark.cores.max=4 \\\n --conf spark.executorEnv.EXT_WH_HOST=$EXT_WH_HOST \\\n --conf spark.executorEnv.EXT_WH_PASSWORD=$EXT_WH_PASSWORD \\\n --conf spark.executorEnv.KAFKA_BROKER_LIST=$_KAFKA_BROKER_LIST \\\n --conf spark.executorEnv.SCHEMA_REGISTRY_URL=$SCHEMA_REGISTRY_URL \\\n --conf spark.executorEnv.AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \\\n --conf spark.executorEnv.AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \\\n --conf spark.executorEnv.STAGING_S3_BUCKET=$STAGING_S3_BUCKET \\\n --conf spark.executorEnv.KAFKA_GROUP_ID=$KAFKA_GROUP_ID \\\n --conf spark.executorEnv.MAX_RATE=$MAX_RATE \\\n --conf spark.executorEnv.KAFKA_MAX_POLL_MS=$KAFKA_MAX_POLL_MS \\\n --conf spark.executorEnv.KAFKA_MAX_POLL_RECORDS=$KAFKA_MAX_POLL_RECORDS \\\n --class com.ticketnetwork.edwstream.external.MapPageView \\\n /opt/edw-stream-external-mpv_2.11-2-SNAPSHOT.jar",

我尝试指定--deploy-mode群集\\ n --master yarn \\ n-相同的错误

错误：

0.0.0.0是默认的主机名属性，而8032是默认的端口号。

获得默认值的原因之一是没有正确设置Hadoop环境变量。您的HADOOP_CONF_DIR必须是Spark的（或Hadoop的）conf文件夹，而不是Spark提取中的基本文件夹。如果使用HiveContext，则此目录必须包含core-site.xml，yarn-site.xml，hdfs-site.xml和hive-site.xml

然后，如果yarn-site.xml位于上述位置，则不需要YARN_CONF_DIR，但是如果您进行了设置，则它必须是实际目录，而不是直接到文件的目录。

此外，您可能需要设置多个主机名。例如，一个生产级YARN群集将具有两个ResourceManagers以实现容错功能。此外，如果启用了某些Kerberos密钥表和主体，则可能需要对其进行设置。

但是，如果您已经有Mesos / Marathon，我不确定为什么要使用YARN

如何激发提交作业到其他群集上的纱线？
