Subject Doubts related to Amazon EMR
Date Mon, 23 Apr 2012 12:42:13 GMT
Hello all,
I want to deploy my task on Amazon EMR. But as I am new to Amazon Web
Services I am confused in understanding the concepts.

My Use Case:

I want to import the large data from EC2 through SQOOP into the Hive.
Imported data in Hive will get processed in Hive by applying some algorithm
and will generate some result (in table form, in Hive only). And generated
result will be exported back to Ec2 again through SQOOP only.

I am new to Amazon Web Services and want to implement this use case with
the help of AWS EMR. I have implemented it on local machine.

I have read some links related to AWS EMR for launching the instance and
about what is EMR, How it works and etc...
I have some doubts about EMR like:

1) EMR uses S3 Buckets, which holds Input and Output data Hadoop Processing
(in the form of Objects). ---> I didn't get How to store the data in the
form of Objects on S3 (My data will be files)

2) As already said I have implemented a task for my use case in Java. So If
I create the JAR of my program and create the Job Flow with Custom JAR.
Will it be possible to implement like this or do need to do some thing
extra for that?

3) As I said in my Use Case that I want to export my result back to Ec2
with the help of SQOOP. Does EMR have support of SQOOP?

If you have any kind of idea related to AWS, please reply me with your
answer as soon as possible. I want to do this as early as possible.

many Thanks.
