Sorry for all the questions, but still trying to get this upgrade done....8 hours into it and all Tasktrackers fail to start with the same error.  Here are the TT logs:

So I understand the message, but have no idea which config file it's getting that string from.

Also, why is the java library and hadoop home pointing at hadoop-0.20.2 post upgrade (yes we did run the -R script post upgrade)???
