FAQ
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.



Best Regards
