------------------------------------
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.
