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.
