      Description

      To support long classpaths on Windows, the class path entries get bundled into a small temporary jar with a manifest that has a Class-Path attribute. When a classpath is specified in a jar manifest like this, it does not expand environment variables (i.e. %HADOOP_COMMON_HOME%), and it does not expand wildcards (i.e. lib/*.jar).
