Harsh J Chouraria updated MAPREDUCE-2225:
-----------------------------------------
Attachment: multipleoutputs.nowritables.r2.diff
Sure, it should avoid a raw types warning I think? Here's a patch for that
update.
> MultipleOutputs should not require the use of 'Writable'

> Key: MAPREDUCE-2225
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2225
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: job submission
> Affects Versions: 0.20.1
> Environment: Linux
> Reporter: Harsh J Chouraria
> Assignee: Harsh J Chouraria
> Priority: Blocker
> Fix For: 0.22.0
>
> Attachments: multipleoutputs.nowritables.r1.diff,
> multipleoutputs.nowritables.r2.diff, multipleoutputs.nowritables.r2.diff
>
> Original Estimate: 1m
> Remaining Estimate: 1m
>
> MultipleOutputs right now requires for Key/Value classes to utilize the
> Writable and WritableComparable interfaces, and fails if the associated
> key/value classes aren't doing so.
> With support for alternates like Avro serialization, using Writables isn't
> necessary and thus the MO class must not strictly check for them.
> And since comparators may be given separately, key class doesn't need to be
> checked for implementing a comparable (although it is good design if the key
> class does implement Comparable at least).
> Am not sure if this brings about an incompatible change (does Java have BIC?
> No idea).
