Unfortunately, it doesn’t get that far in my code where I have a SparkContext
from which to set the Hadoop config parameters. Here is my Java code:
SparkConf sparkConf = new SparkConf()
.setJars(new String[] {
"file:///opt/wildfly/mapreduce/mysparkjob-5.0.0.jar", })
.setSparkHome("/usr/hdp/" + getHdpVersion() + "/spark")
.set("fs.defaultFS", config.get("fs.defaultFS"))
;
sparkContext = new JavaSparkContext("yarn-client", "SumFramesPerTimeUnit",
sparkConf);
The job dies in the constructor of the JavaSparkContext. I have a logging call
right after creating the SparkContext and it is never executied.
Any idea what I’m doing wrong? David

Subject: Re: Problem submitting a spark job using yarn-client as master
you can set hdfs as defaults,
sparksession.sparkContext().hadoopConfiguration().set("fs.defaultFS",
“hdfs://master_node:8020”);

I am trying to submit a spark job through the yarn-client master setting. The

Notice that the file __spark_conf__1435451360463636119.zip is not copied
because it exists, I believe on the hdfs. However when the client goes to fetch
it, it is reporting that it does not exist, probably because it is trying to
get it from “file:/tmp” not the hdfs. Any idea how I can get this to work?
