If you ever search for spark + s3 on stack overflow you can see that the #1 recurrent complaint is ["I added hadoop-aws-3.1 to hadoop and now I get a class not found exception](https://stackoverflow.com/questions/52310416/noclassdeffounderror-org-apache-hadoop-fs-streamcapabilities-while-reading-s3-d/). This is why the S3A troubleshooting docs start by telling people not to mix jars as all they do is move stack traces around https://hadoop.apache.org/docs/current3/hadoop-aws/tools/hadoop-aws/troubleshooting_s3a.html#Classpath_Setup I don't want to make things worse. if you don't want the aws sdk, don't include it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
