You should file a Jira on this (with your traces etc).
done. https://issues.apache.org/jira/browse/HADOOP-1489 a couple questions. - When including code/stack trace, my input was nicely indented, but after submission, somehow the text formatting fields are all mess up. (e.g., the entire code segment became one line). Is attachment the only way to do this right? - To track this, I essentially was doing "printf" debugging. It is rather slow/painful. Is there a way to get suspend the tasks, which will then allow people to attach a debugger in time to trace thru the execution. If not, how do people generally debug problems like this? I generally find the ability to debugger-attach to programs and just roam around the stack helps greatly in understanding complex programs quickly (even if I am not looking for bugs). bwolen
