java.io.EOFException on Spark EC2 Cluster when submitting job programatically

Question

realy need your help to understand, what I'm doing wrong.

The intent of my experiment is to run spark job programatically instead of using ./spark-shell or ./spark-submit (These both work for me)

Environment: I've created a Spark Cluster with 1 master & 1 worker using ./spark-ec2 script

Cluster looks good, however, when I try to run the code being packaged in a jar:

val logFile = "file:///root/spark/bin/README.md"

val conf = new SparkConf()
conf.setAppName("Simple App")
conf.setJars(List("file:///root/spark/bin/hello-apache-spark_2.10-1.0.0-SNAPSHOT.jar"))
conf.setMaster("spark://ec2-54-89-51-36.compute-1.amazonaws.com:7077")

val sc = new SparkContext(conf)

val logData = sc.textFile(logFile, 2).cache()
val numAs = logData.filter(_.contains("a")).count()
val numBs = logData.filter(_.contains("b")).count()
println(s"1. Lines with a: $numAs, Lines with b: $numBs")

I get an exception:

What I'm actualy doing is a call "sbt run". So I assemble the scala project and run it. By the way, I run that project on a master host, so the driver definitely is visible for a worker host. Any help is appreciated. That's very strange, that such a simple example doesn't work in cluster. Using ./spark-submit is not convenient, I believe. Thanks in advance.

Answer 1

After wasting a lot of time, I've found the problem. Despite I haven't used hadoop/hdfs in my application, hadoop client matters. The problem was in hadoop-client version, it was different than the version of hadoop, spark was built for. Spark's hadoop version 1.2.1, but in my application that was 2.4.

When I changed the version of hadoop client to 1.2.1 in my app, I'm able to execute spark code on cluster.
