Subject Re: Doubts related to Amazon EMR

It is possible to install Sqoop on AWS EMR. I've got some scripts I can publish later. You
are not required to use S3 to store files and can use the local (temporary) HDFS instead.
After you have Sqoop installed, you can import your data with it into HDFS, run your calculations
in HDFS, then export your data back out using Sqoop again.
