mapred/yarn scripts should use lib/'*' instead looping the dir for jar to
create the classpath
----------------------------------------------------------------------------------------------
Key: MAPREDUCE-3745
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3745
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 0.23.1, 0.24.0
Reporter: Alejandro Abdelnur
Fix For: 0.23.1
The scripts do a for loop on the JAR contents of the directory, they should
just use '*' in the classpath, ie lib/'*'
This will reduce the length of the generated classpath significantly
