Subject ArrayWritable as Map/Reduce output value
Date Wed, 24 Nov 2010 07:52:23 GMT

I am a beginner to Hadoop. Can anyone suggest me how to define Map/Reduce
output value as an ArrayWritable?

The output value must contain array of integers.
eg. (img1 , value[] { x-coord, y-coord, R, G, B})

How can the individual fields of the ArrayWritable can be accessed using the
Iterator in the Reduce function? And also how to write the ArrayWritable
object to the output file?
