Through the UI Amazon's framework allows me to create jobs with multiple inputs by specifying multiple --input lines. e.g.:
-input s3n://something -input s3n://something-else
Similarly the Ruby EMR client has been very helpful to me so far: http://aws.amazon.com/developertools/2264
However, I'm trying to script a nightly job that requires multiple inputs and I can't seem to find any way to do this. It won't let me pass multiple -input parameters and when I use --arg or --args the job that is created does not contain the -input lines. It is almost as if it is stripping it out.
Has anybody used this tool for this purpose successfully?
