Caused by: java.lang.ClassNotFoundException: org.jets3t.service.ServiceException - scala

Question

My code should access some file stored on S3 (this code works fine on one machine, while it fails on the other one; basically it fails when it gets executed locally (not on the cluster) from Intellij IDEA):
sc.hadoopConfiguration.set("fs.s3n.impl", "org.apache.hadoop.fs.s3native.NativeS3FileSystem")
sc.hadoopConfiguration.set("fs.s3n.awsAccessKeyId", "xxx")
sc.hadoopConfiguration.set("fs.s3n.awsSecretAccessKey", "xxx")
val sqlContext = new SQLContext(sc)
var df = sqlContext.read.json("s3n://myPath/*.json")
I get the following error at the line var df = sqlContext.read.json("s3n://myPath/*.json"):
Caused by: java.lang.ClassNotFoundException: org.jets3t.service.ServiceException

I read similar threads regarding this issue and it was mentioned that in case of using Spark 1.6.2, the solution is to use org.apache.hadoop hadoop-aws 2.6.0. In my case it has not solved the problem.
My pom.xml (an extract from it):

Answer 1

Adding the following in the dependency should solve the issue
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-client</artifactId>
<version>2.6.0</version>
</dependency>
I hope this helps
