I am trying to run the Big Data benchmark
<https://amplab.cs.berkeley.edu/benchmark/> on my EC2 cluster for my own
Spark fork of version 1.5. It just modifies some files on the Spark core. My
cluster contains 1 master and 2 slave nodes of type m1.large. I use the ec2
scripts bundled with Spark to launch my cluster. The cluster launched
perfectly and I am able to successfully ssh into the master. However when I
try to run the benchmarks from the master using the command
./runner/prepare-benchmark.sh --shark --aws-key-id=xxxxxxxx
--aws-key=xxxxxxxx --shark-host=<my-spark-master>
--shark-identity-file=/root/.ssh/id_rsa --scale-factor=1
I get the following error:
=== IMPORTING BENCHMARK DATA FROM S3 ===

have tried terminating the cluster and launching it again multiples times
but the problem persists. What could be the issue?
