Ignore first record of a file

I have a file as follows:


event_time        session_id
12334545          67890087
 56788898         87689000


I do not want to read the first record of file which consists of  column
names.

How to write a PIG script for this


Thanks

Perhaps the general way to do this is to write a custom loader, but for
this simpler usecase, can you just filter out the record?

FILTER ... BY $0 MATCHES '^[0-9]+'
