Paul Vasilev reassigned MAPREDUCE-6053:
---------------------------------------
Assignee: Paul Vasilev
> New hadoop API don't allow dynamic key-based names for output files
> -------------------------------------------------------------------
>
> Key: MAPREDUCE-6053
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6053
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: job submission
> Reporter: Paul Vasilev
> Assignee: Paul Vasilev
>
> MultipleTextOutputFormat class removed from new api. MultipleOutputs class
> forces developer to set names of output files at job configuration time.
> So with new api I can't create files with names based on keys (I don't know
> all keys. Therefore I can't set output file names at job configuration time).
> This is major disadvantage in comparison with old api and force developer to
> use it.
