Subject Re: Hadoop on EC2 - public AMIs in hadoop-images
Date Mon, 07 Sep 2009 15:14:24 GMT
Thanks for the replies, I've been developing against 0.18.3 under Windows XP
and testing on Ubuntu.

That seems like a long list of changes from 0.18.3! Should I expect any
specific issues if I try Cloudera's version on EC2 seeing as I have only
tested against the stock 0.18.3?

Cheers,
John
