Configuration should trim whitespace around class name values
-------------------------------------------------------------
Key: HADOOP-6578
URL: https://issues.apache.org/jira/browse/HADOOP-6578
Project: Hadoop Common
Issue Type: Improvement
Components: conf
Affects Versions: 0.22.0
Reporter: Todd Lipcon
Priority: Minor
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.
