Sean Busbey updated HADOOP-10115:
---------------------------------
Component/s: build
Description:
In the hadoop package distribution there are more than 90% of the jars are
duplicated in multiple places.
For Ex:
almost all jars in share/hadoop/hdfs/lib are already there in
share/hadoop/common/lib
Same case for all other lib in share directory.
Anyway for all the daemon processes all directories are added to classpath.
So to reduce the package distribution size and the classpath overhead, remove
the duplicate jars from the distribution.
