Resolution: Duplicate

Duplicate of HADOOP-333
> we should automate checks of the output of the sort example program

> Key: HADOOP-877
> URL: https://issues.apache.org/jira/browse/HADOOP-877
> Project: Hadoop
> Issue Type: Improvement
> Components: test
> Affects Versions: 0.10.0
> Reporter: Owen O'Malley
>
> Since we are using the sort example program to do smoke tests on new versions
> of Hadoop, it would be nice to have some checks of the output. The checks
> that I've considered:
> 1. count the number of records on input & output
> 2. compute the md5 of each key/value and xor across all of the rows
> 3. use a map/reduce job to merge the input and output directories and make
> sure that each key/value appears on both input and output
