Hi,
Is there anyway I can ignore all keys except a certain key ( determined
after the map stage) to start only 1 reduce job using a partitioner? If so
could someone suggest such a method.
Regards,

Hi,
When do you know the keys to ignore ? You mentioned after the map stage
.. is this at the end of each map task, or at the end of all map tasks ?
Thanks

Hi,
Consider it to be a single iteration Kmeans clustering job such that I only
wish to schedule reduce jobs for the clusterId(the key for a Kmeans) of the
cluster corresponding to the 1st point in the dataset.
I wish to check the clusterId of the first point in the input file and get
reduce jobs
