Subject [jira] [Updated] (HADOOP-10115) Exclude duplicate jars in hadoop package under different component's lib
Date Mon, 09 Mar 2015 15:35:38 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-10115?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
