> As discussed on HADOOP-7328, MapReduce can handle serializers in a much
> better way in case of bad configuration, improper imports (Some odd Text
> class instead of the Writable Text set as key), etc..
> This issue covers the MapReduce parts of the improvements (made to IFile,
> MapOutputBuffer, etc. and possible early-check of serializer availability
> pre-submit) that provide more information than just an NPE as is the current
> case.
