Installing Spark on i386 architecture

Hello all,

I've done my due diligence searching, and can't seem to find a solution:

I'm running CentOS 6.5 on i386 architecture (because it's on an antique Lenovo T60 laptop, which btw it runs great on - can't say the same for any recent Windows OS's, big surprise...).  Unfortunately, the most recent version of Spark seems to only run on x86_64 architecture.  Is there an alternative or older version that I can install instead?

Thanks so much,

Lyxix
