Your partitioner can implement Configurable (setConf(conf) and
getConf()). Please see
org.apache.hadoop.mapreduce.lib.partition.BinaryPartitioner

Thanks a lot for your information, Tom.
I am using the org.apache.hadoop.mapreduce.Partitioner in 0.20. It seems that
the org.apache.hadoop.mapred.Partitioner is deprecated and will be removed in
the futture.
Do you have some suggestions on this?
Thanks,
Jianmin

Hi Jianmin,
Partitioner extends JobConfigurable, so you can implement the
configure() method to access the JobConf.
Hope that helps.
Cheers,
Tom

Hi,
I am considering to implement a Partitioner that needs to access the parameters
in Configuration of job. However, there is no straightforward way for this
task. Are there any suggestions?
Thanks,
