[URGENT] Help with using extra information while processing input data using map technique

[Pallavi P <pa...@gmail.com>]

Hi All,
 I am new to hadoop and learning how to use it. I have a problem which can
be solvable using map-reduce technique. But, in my map step, I need to
consider some extra information which depends on  the input key,value pair.
Can some one please help me what is the good way of taking this data? I am
thinking of storing it in some HDFS and map code try to load it whenever it
is processing a particular key, value pair. any other better approaches,
please let me know.

Thanks & Regards
Pallavi

MapReducerBase has a method configure(JobConf jobconf). You might use the
method to initialize the extra information that your map needs.
