Junping Du updated MAPREDUCE-6454:
----------------------------------
Attachment: MAPREDUCE-6454.patch
MRApps already include files in distributed cache when adding them to classpath
env of MRApps. However, "jar"s are excluded for some reason (seems not valid
now). In this patch, we add it back.
> MapReduce doesn't set the HADOOP_CLASSPATH for jar lib in distributed cache.

>
> We already set lib jars on distributed-cache to CLASSPATH. However, in some
> corner cases (like: MR local mode, Hive Map side local join, etc.), we need
> these jars on HADOOP_CLASSPATH so hadoop scripts can take it in launching
> runjar process.
