如何将作业提交给其他集群上的纱线？

Question

我有一个安装了spark的docker容器，我正试图使用马拉松将作业提交给其他集群上的yarn。docker容器有yarn和hadoop conf dir的导出值，yarn文件还包含正确的emr主ip地址，但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"

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

  "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",

错误：

Answer 1

0.0.0.0是默认的主机名属性，8032是默认的端口号。

得到默认值的一个原因是两个Hadoop环境变量都没有正确设置。您的Hadoop_conf_dir需要是Spark的（或Hadoop的）conf文件夹，而不是Spark提取的基本文件夹。如果使用HiveContext，此目录必须包含core-site.xml、yarn-site.xml、hdfs-site.xml和hive-site.xml

那么，如果yar-site.xml位于上面的位置，则不需要yarn_conf_dir，但是如果要设置它，它需要是一个实际的目录，而不是直接指向文件。

此外，您可能需要设置不止一个主机名。例如，一个生产级纱线集群将有两个容错资源管理器。此外，如果启用了Kerberos键选项卡和主体，则可能需要设置这些键选项卡和主体。

如果你已经有Mesos/Marathan，我不知道你为什么要用纱线
