Hello,
I'm getting the following messages when I try to run a job I've developed.
hadoop jar distanceCalc.jar DistanceCalc distanceCalculations
distanceCalculations/output9

I'm obviously doing something wrong in the code but my question for this
thread is the warning message I'm receiving. I'm not quite sure what it
means and what I've seen on google so far is the warning has something to do
with Pig but I'm not using Pig. Can someone tell me what the warning means
please?
Thanks for your time
Erik
