issue with s3 and new bucketname about secor

[ppearcy]

Had same problem.

The key problem here is that HMAC v2 is being used and eu-central-1 requires v4. Looks like there is work needed in HadoopS3UploadManager to support this. Needs to switch to s3a and add option to set the endpoint so jets3t can do the right thing.

I was able to get eu-central working using S3UploadManager, though. I needed to exclude the aws sdk brought in by hadoop-aws while compiling since it causes various classloader issues with the latest aws sdk. Secor's jar deps is sort of becoming a mess as more and more is getting pushed into the core app vs a plugin approach.

Then I needed to ensure that endpoint or region is set and things work.

After spending two hours and weird messages at the end found that the bucket that I was creating was in frankfurt region. I can not find any reason why writing fails in that region maybe policy issue. Anyway that was the issue!!
