Jonathan Coveney commented on PIG-2855:
---------------------------------------
Love the idea.
One potential issue... with POUser func, it looks like your counter group is
FuncSpec#toString, which means multiple invocations of the same UDF in
different parts of the code will go to the same counter.
> Provide a method to measure time spent in UDFs

> When debugging slow jobs, it is often useful to know whether time is being
> spent in UDFs, and in which UDFs. This is easy to measure from within the
> framework, we should let users optionally track these metrics.
