Subject Re: Creation of an empty output directory in hadoop filesystem

Vandana,

Also, in the code that you attached, I see 2 compilation errors. How is it
even compiling? Or am I missing something here?

1- The 'sum' is not declared in the Map class.
2- The 'sum' in the Reduce class, when written to the context needs to be
IntWritable and not directly an int.

Regards,
Shahab
