YARN REST API - Spark job submission

I am trying to use the YARN REST API to submit the spark-submit jobs, which I generally run via command line.

My command line spark-submit looks like this

JAVA_HOME=/usr/local/java7/ HADOOP_CONF_DIR=/etc/hadoop/conf /usr/local/spark-1.5/bin/spark-submit \
--driver-class-path "/etc/hadoop/conf" \
--class MySparkJob \
--master yarn-cluster \
--conf "spark.executor.extraClassPath=/usr/local/hadoop/client/hadoop-*" \
--conf "spark.driver.extraClassPath=/usr/local/hadoop/client/hadoop-*" \
spark-job.jar --retry false --counter 10

Reading through the YARN REST API documentation https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Applications_APISubmit_Application, I tried to create the JSON payload to POST which looks like

{
  "am-container-spec": {
    "commands": {
      "command": "JAVA_HOME=/usr/local/java7/ HADOOP_CONF_DIR=/etc/hadoop/conf org.apache.hadoop.yarn.applications.distributedshell.ApplicationMaster  --jar spark-job.jar --class MySparkJob --arg --retry --arg false --arg --counter --arg 10"
    }, 
    "local-resources": {
      "entry": [
        {
          "key": "spark-job.jar", 
          "value": {
            "resource": "hdfs:///spark-job.jar", 
            "size": 3214567, 
            "timestamp": 1452408423000, 
            "type": "FILE", 
            "visibility": "APPLICATION"
          }
        }
      ]
    }
  }, 
  "application-id": "application_11111111111111_0001", 
  "application-name": "test",
  "application-type": "Spark"   
}

The problem I see is that, the hadoop configs directory is previously local to the machine I was running jobs from, now that I submit job via REST API and it runs directly on the RM, I am not sure how to provide these details ?

If you are trying to submit spark job via REST APIs, I will suggest to have a look at Livy. Its a simple and easiest way to submit spark jobs to cluster.

Livy is an open source REST interface for interacting with Apache Spark from anywhere. It supports executing snippets of code or programs in a Spark context that runs locally or in Apache Hadoop YARN.
