[jira] [Created] (MAPREDUCE-3745) mapred/yarn scripts should use lib/'*' instead looping the dir for jar to create the classpath

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

[jira] [Commented] (MAPREDUCE-3745) mapred/yarn scripts should use lib/'*' instead looping the dir for jar to create the classpath

Mahadev konar commented on MAPREDUCE-3745:
------------------------------------------

@Alejandro,
 I think only bin/mapred does that. bin/yarn should be fixed.
