> MRUnit Allows Iteration Twice
> -----------------------------
>
> Key: MAPREDUCE-1128
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1128
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 0.20.1
> Environment: Java 1.6, Hadoop 0.21.1+133 (cloudera distribution for
> hadoop)
> Reporter: Ed Kohlwey
> Assignee: Aaron Kimball
> Priority: Minor
> Attachments: MAPREDUCE-1128.patch
>
> Original Estimate: 0.5h
> Remaining Estimate: 0.5h
>
> MRUnit allows one to iterate over a collection of values twice (ie.
> reduce(Key key, Iterable<Value> values, Context context){
> for(Value : values ) /* iterate once */;
> for(Value : values ) /* iterate again */;
> }
> Hadoop will allow this as well, however the second iterator will be empty.
> MRUnit should either match hadoop's behavior or warn the user that their code
> is likely flawed.
