I'm trying Common Crawl w/ Hadoop 0.20.205 and I'm getting the following:

I've tried clean builds, etc. Anyone have any ideas? AIUI, this error usually comes from version mismatches. I deleted the jetst 0.6 version in my Hadoop lib directory, but I suspect there is an older version somewhere else in the classpath. Anyone else seen this?
