Todd Lipcon commented on HADOOP-8206:
-------------------------------------
bq. Makes sense to me. One question, though - we seem to be inconsistently
using IllegalArgumentException and HadoopIllegalArgumentException. Is there any
good reason for that?
I'm not entirely sure -- looking across the code as a whole, we have a 10:1
ratio of IllegalArgumentException vs HadoopIllegalArgumentException. So I'm
erring on the side of what's used more often, except in a few places where we
directly expose it as a potentially user-visible error (like bad command line
arguments).
