michal pointed out we don't really do any import of s3 in jenkins anymore, because we switched to import hdfs/s3n so we could point to a subfolder and only import the subfolder (speed). import s3 requires you to import the whole bucket, and h2o traverses all of the files in the bucket. In the past I noticed when tomas fixed it to traverse the whole bucket we now take up to 7 minutes for the import. That's why I switched the jenkins redirect of import folder tests from using s3 to using hdfs/s3n pointing ot lower subdirs.

test test is added to use import s3 so we have an import s3 test in jenkins.

It's possible to make the import folder tests redirect to s3 instead of hdfs/s3n by changing the ec2 config json from the default:
redirect_import_folder_to_s3n_path: true

to
redirect_import_folder_to_s3_path

h2o_import supports that. So that's another way to get import s3 testing, although some tests will timeout on the import folder, I think.
