List of Puts in mapreduce java job

[Silvio Di gregorio]

Hi
I'm trying to emit, on reduce phase, a list of puts

*context.write(null , puts);*

puts is

*List<Put> puts=new ArrayList<Put>();*

and the Reduce signature is:

*public static class Reduce extends TableReducer<IntWritable, Text,
ImmutableBytesWritable>{*

this is the error

*The method write(ImmutableBytesWritable, Mutation) in the type
TaskInputOutputContext<IntWritable,Text,ImmutableBytesWritable,Mutation> is
not applicable for the arguments (null, List<Put>)*

thanks
silvio
