Hadoop error when using spark-submit

Question

I am trying to spark-submit using Amazon ec2 with the following:

spark-submit --packages org.apache.hadoop:hadoop-aws:2.7.1 --master spark://amazonaws.com SimpleApp.py

and I end up with the following error. It seems to be that it is looking for hadoop. My ec2 cluster was created using spark-ec2 command.

Answer 1

Sorry everyone, it was just some local proxy issues.

Answer 2

You are submitting the job with --packages org.apache.hadoop:hadoop-aws:2.7.1 option and job is attempting to resolve the dependencies by downloading the packages from public maven repo. However, this error indicates it's unable to reach the maven repo.

Server access error at url https://repo1.maven.org/maven2/org/apache/hadoop/hadoop-aws/2.7.1/hadoop-aws-2.7.1.pom (java.net.NoRouteToHostException: No route to host (Host unreachable))

You might want to check if the spark master has access to internet.
