How to read specific jar from classpath (having multiple version of common-codec in classpath)

Expert Contributor

My application need common-codec1.10 version but on cluster i have 1.4, when i launch yarn application using hadoop_classpath=/home/*/common-codec-1.10.jar:o yarn jar <*.jar> yarn picks up 1.4 first then after it has 1.10. so i am getting exception on method not found. How can tell yarn application to read through full classpath instead to read till 1.4 and stop.
