Subject: Implementing a grouping comparator with avro
From: Frank Kootte <frankkootte@gmail.com>
To: user@hadoop.apache.org
Content-Type: multipart/alternative; boundary=0015175d03941b076b04c96ec4c8

Content-Type: text/plain; charset=ISO-8859-1

I need to implement secondary sort within an avro based MR sequence. I
however find little to documentation or examples online.
I would like to implement this by overriding the  'int
compare(AvroWrapper<T> x, AvroWrapper<T> y)' method but I fail to have it
invoked.
Does anybody have experience implementing secondary sort on deserialised
avro objects ?

Some help, advise or pointers will be very much appreciated !
