Hey, I am making some calls with Boto3 in my pyspark which is working fine in master=local mode but when I switch to master=yarn I am getting "NoCredentialsError: Unable to locate credentials" which is a bit annoying as I cannot work out why!
I have been running this application fine on Mesos and EMR. Does HDP PySpark2 run within a virtualenv or something? Cheers, Andrew -- Otter Networks UG http://otternetworks.de Gotenstraße 17 10829 Berlin
