Re: SequenceFileOutputFormat - Custom Type Key & Value
You NO need to do anything specifically to emit Text, VectorWritable into
your SequenceFileOutputFormat.
Rather you need to just emit the Key as Text and value as VectorWritable in
your Reducer method.
And just set the setOutputKeyClass and setOutputValueClass with these on
your JobConf or Job instances based on how you are defining the MR job.
