Hello,
I have been trying to run the sample sort program, but I could not even run
the randomwriter to generate random data to be sorted.
Here is the beginning of the error message:
07/03/03 06:12:15 INFO mapred.InputFormatBase: Total input paths to process

Could anyone suggest what went wrong or how to correct this?? Thank you.
