Re: Do I still need hadoop-aws libs when using Flink 1.5 and Presto?

Thanks for pick up my question. I had s3a in the config now I removed it.
I will post a full trace soon, but want to get some questions answered to help me understand this better.

1. Can I use the presto lib with Flink 1.5 without bundled hdp? Can I use this?
2. How do I configure presto for endpoints, encryption? The S3A file system needed core-site.yml to configure such things and S3 V4 signature. Do I have to do it for presto?
3. If yes, how to do it? Just add to flink-config? 
    like s3.server-side-encryption-algorithm: AES256
    s3.endpoint: '' other values for France regions, etc

I will post more logs when I get one. Thanks

what are you using as the FileSystem scheme? s3 or s3a?

Also, could you also post the full stack trace, please?

I am trying to figure out how to use S3 as state storage.

Seems like I only have to do two things:
1. Put flink-s3-fs-presto to the lib
2. Configure
s3.access-key: your-access-key
s3.secret-key: your-secret-key

But I see this exception: ClassNotFoundException: NativeS3FileSystem/S3AFileSystem Not Found

Add it is suggested to add more libs.
So I am confused here, is there a step 3 needed? Isn't the presto jar is all self contained?
