Michele Catasta commented on HADOOP-6578:
-----------------------------------------
Javadoc warnings are coming from the hadoop.security package.
ORing with the previous Hudson run in March, it should be a +1 overall.
> Configuration should trim whitespace around a lot of value types

> I've seen multiple users make an error where they've listed some whitespace
> around a class name (eg for configuring a scheduler). This results in a
> ClassNotFoundException which is very hard to debug, as you don't notice the
> whitespace in the exception! We should simply trim the whitespace in
> Configuration.getClass and Configuration.getClasses to avoid this class of
> user error.
> Similarly, we should trim in getInt, getLong, etc - anywhere that whitespace
> doesn't have semantic meaning we should be a little less strict on input.
