when submit spark2 program on Yarn with Java, how can I specify --file option


Hi experts:

Currently I want to use java servlet to get some parameters from a http request and pass them to my spark program by submit my spark program on Yarn in my java code. Follow demo on, I can submit a demo program with this code. Basically, it use



However, for my own program, I need to specify --file option to provide hive-site.xml to my program like

./spark-submit --class XXX XXXX.jar --file /XXX/XXX/hive-site.xml --arg XXXX

but in spark2 it seems "--file" option is not been supported. But in spark 1.6.2 It can be supported.

In these case, is there any other way I can set --file option in my java program?

Thanks a lot



Or is there any other way I can submit spark on Yarn in my Java program?

It is ok to submit a job with spark2-submit. What I try to do it to submit a job in my java servlet, as we need to trigger a job submission by a http request, as following:

String request = request.getParameter("XXXX")
org.apache.spark.SparkConf sparkConf = new org.apache.spark.SparkConf();
sparkConf.set("spark.submit.deployMode", "cluster"); 

String[] commandArgs = new String[]{
        		"--class","XXX","--file","hdfs://XXXX/hive-site.xml,/XXX/XXX/","--jar","/XXX/XXXX.jar","--arg", request };
org.apache.spark.deploy.yarn.ClientArguments cArgs = new org.apache.spark.deploy.yarn.ClientArguments(commandArgs);
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration(); 
conf.set(..)//set resource manager address etc
org.apache.spark.deploy.yarn.Client client = new org.apache.spark.deploy.yarn.Client(cArgs, conf, sparkConf);;

The problem is when in spark 1.6.2, "--file" in commandArgs can be used in ClientArguments, but in Spark 2.0 above, it seems that ClientArguments does not support "--file" any longer. Then I do not know how can I pass such option to spark cluster on Yarn

You should be able to use SparkConf set method to set spark.files to your hive-site.xml. Here is the JIRA that I that talks about removing ClientArguments and make it private from Spark 2.0 onwards.
