Subject [jira] [Created] (HADOOP-13070) classloading isolation improvements for cleaner and stricter dependencies
Date Thu, 28 Apr 2016 23:21:12 GMT
Sangjin Lee created HADOOP-13070:

             Summary: classloading isolation improvements for cleaner and stricter dependencies
                 Key: HADOOP-13070
                 URL: https://issues.apache.org/jira/browse/HADOOP-13070
             Project: Hadoop Common
          Issue Type: Improvement
          Components: util
            Reporter: Sangjin Lee
            Assignee: Sangjin Lee
            Priority: Critical

Related to HADOOP-11656, we would like to make a number of improvements in terms of classloading
isolation so that user-code can run safely without worrying about dependency collisions with
the Hadoop dependencies.

By the same token, it should raised the quality of the user code and its specified classpath
so that users get clear signals if they specify incorrect classpaths.

This will contain a proposal that will include several improvements some of which may not
be backward compatible. As such, it should be targeted to the next major revision of Hadoop.
