Steve Loughran commented on HADOOP-6287:
----------------------------------------
Also, what happens when you try to getInt() a value that is out of range of an
integer? I believe historically Integer.parseInt() would throw a
NumberFormatException which would lead to the default. Trying to cast a long to
an int may be a different behaviour.
# Tests need to establish what the current behaviour is
# New code needs to maintain that behaviour -if everyone agrees that the old
behaviour was the correct one.

> We should add support for units in our Configuration system so that we can
> specify values to be *1GB* or *1MB* rather than forcing every component which
> consumes such values to be aware of these.
