-Re: Using space as field separator fails. How do I fix this?

I had a similar problem though my logs were terminated with carriage
return. Many of the fields in my logs are deliminated with a space. We
tried using \s but that basically removed every instance of the letter s
(yeah I thought that was amusing too). In some cases we were able to do
a \\t but that didn't seem to work with our logs very well. We are
using the regex SerDe and using a regex deliminator we hand built to
make it work. So far so good. Perhaps this is where you need to go.
I'm still learning how that works myself. Exciting Stuff!!
