Using Hyracks to test MapReduce (Hadoop) code

[Angelos Vasilakopoulos]

I have installed Hyracks locally and successfully followed the "First Hyracks Example" instructions.

I am familiar  and already tested  code with Hadoop, but I have difficulties on how to test it in Hyracks.

The code I want to test is a single java Hadoop program that defines Hadoop Map and Reduce functions. 

How should I proceed to test it in Hyracks? Probably I should start by using "Hadoop compatibility layer" instructions. 

Where can I find the Hadoop compatibility layer archive file  "hadoop_compatibility.tar.gz"? I did not find it (or its scripts directory) in Hyracks svn directory. 

(If, on the other hand, I put my Hadoop code direcly in Hyracks as a main java file I get build errors like "package org.apache.hadoop.io does not exist" , "cannot find symbol 'class Mapper' ").

Thank you in advance, 
Angelos
