Re: Issue while running Pig in Hadoop mode
Hi Nikhil,

Can you paste your script here or pastebin?

The warning message says you are trying to access a field that does not
exist. An easy way to debug would be to make sure you have records flowing
out of each Pig statement. You can use LIMIT operator to dump 10 records or
so and troubleshoot the pig statement at which you are losing records.
