You are using Java6, correct? well, in that case something being passed down to setXIncludeAware may be picked up as invalid. More of a stack trace may help. Otherwise, now is your chance to learn your way around the hadoop codebase, and ensure that when the next version ships, your most pressing bugs have been fixed

stable version
Hi! Kind of novice question, but I need to know, what Hadoop version is considered stable. I was trying to run version 0.19, and I've seen numerous stability issues with it. Maybe version 0.18 is better suited for production environment? Vadim
Most stable version of Hadoop
