Description
We have users who have organized data by day and would like to select several days in a single input specification. For example they would like to be able to say:
'/data/2007
{0830,0831,0901}/typeX/'
To input 3 days data into map-reduce (or Pig in this case).
(Also the use of regexp to resolve glob paterns looks like it might introduce some other bugs. I'd appreciate it if someone took another look at the code to see if there are any file characters that could
be interpreted as regexp "instructions").
