Any ideas on what the error below indicates would be very helpful.
Let me know if I can provide any additional info.
I am using Hadoop 0.20.2+737.

Amici,

Maybe you could attach your job and transformations ?

Amici,

That error was from an internal developer build and has since been fixed. It happens a mapper is allocated and not used.

Thanks for the feedback.
