Radim Kolar commented on MAPREDUCE-4068: ---------------------------------------- I do not see it either. Its major problem while migrating from mrv1. Libs in lib/ are used only in hadoop driver during job submission, but not in map/reduce YarnChild.java > Jars in lib subdirectory of the submittable JAR are not added to the classpath > ------------------------------------------------------------------------------ > > Key: MAPREDUCE-4068 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4068 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.1 > Reporter: Ahmed Radwan > Fix For: 0.23.2 > > > Prior to hadoop 0.23, users could add third party jars to the lib > subdirectory of the submitted job jar and they become available in the task's > classpath. I see this functionality was in TaskRunner.java, but I can't see > similar functionality in hadoop 0.23 (neither in MapReduceChildJVM.java nor > other places). -- This message is automatically generated by JIRA.
