Subject [jira] [Commented] (MAPREDUCE-5615) Off-the-shelf funtionality for processing of Image, Video, Audio files
Date Fri, 08 Nov 2013 09:36:18 GMT

Steve Loughran commented on MAPREDUCE-5615:
-------------------------------------------

This could be good, but it may be better outside the core hadoop project simply because it
can evolve and release on a separate timetable. If so, where should it go? Mahout isn't quite
the right place

> The FileInputFormat,FileOutputFormat, FileRecordReader, FileRecordWriter 
> are not ideal for processing of media data types.
> Believe most use SequenceFile and repeat their own set of media transcoding /processing
to enable big data processing for them.
> There might be few non open source implementations to handle image, video, audio processing.Maybe
MapR has some impl.
> Suggest we have standard off-the-shelf functionality to handle these kind of input datatypes
