hi, how can i specify which class' main method to run as a job when i do mapreduce? lets say my jar has 4 classes and each one of them has a main method. i want to pass the class name in the 'hadoop jar <jar file> <classname>' command. this will be similar to running stock tools inside hbase or other hadoop jars that out of the box. currently, i solve this problem by setting the main in the project and building the jar and running it. but i want to be able to flip that at run time instead of compile time.
thanks
