Hi Tharinda,

Please find the comments inline.

I think the major part of this project is create a back end of java code

Yes.

Wrangler scripts are mostly done by javascript. So I need to convert those

Yes. Further, java code should be Apache Spark Transformation. Please refer
my previous mail for details on Spark.

I was not able to find some method. Other ways of doing this is used common

You have to come up with a solution and an implementation for this. It is
the core part of the project :)

Feel free to contact us if you need further clarifications.

Supun
