Thanks for the reply. I import it to my second program library. I don't
know how to call my MR class methods (for example WordCount Program) in the
second program..? I do MYProg myprog = new MYProg(); and now I should call
a mapreduce method. what method should I call to execute the first
mapreduce class?

in your second java program's java file, import classes you want from
the 1st mapreduce class.
import packagename.class;
...
compile:
java -cp /<path>/yourMRClass.jar yourSecondClass
