> hadoop-config.cmd, sets the class path by listing each jar file to the 
> CLASAPATH. Many times the downstream components use hadoop_config.cmd to set 
> the CLASAPATH for hadoop jars. After adding their own class path, many times 
> the classpath length is hitting the windows command lenght limit.
> We should try to use classpath wildcards to reduce the length of the 
> classpath.
