How to submit Spark Streaming application to yarn cluster?

You will learn how to submit Spark Streaming application to a YARN cluster to avoid sleepless nights during on-call hours. In the YARN cluster mode Spark driver runs in the same container as the Application Master, the first YARN container allocated by the application.

Re: Spark job fails in cluster mode. 2) you only provide application.conf in –file list, there’s no log4.properties. So either you have this log4.properties distributed on each YARN node, or you should add this log4.properties file to –file list, and reference it with “-Dlog4j.configuration=./log4.properties” Re: Spark job fails in cluster mode.

In cluster mode, the Spark driver runs inside an application master process which is managed by YARN on the cluster, and the client can go away after initiating the application. In client mode, the driver runs in the client process, and the application master is only used for requesting resources from YARN.

A long-running Spark Streaming job, once submitted to the YARN cluster should run forever until it is intentionally stopped. Any interruption introduces substantial processing delays and could lead to data loss or duplicates. Neither YARN nor Apache Spark have been designed for executing long-running services.

In yarn-cluster mode reading a file means it must be available on hdfs (if I’m right?) and my file is being copied to path like this: Where I can of course read it, but I cannot find a way to get this path from any configuration / SparkEnv object. And hardcoding .sparkStaging in spark code seamed like a bad idea.

spark.yarn.dist.files would have stored it as file:/home/xyz/file1.properties,file:/home/xyz/file2.properties hence splitting the string by (,) and (/) so that i can eliminate the rest of the content except the file name.
