--------------------------------------

             Summary: some standard JDK APIs are not part of system classes defaults
                 Key: MAPREDUCE-5878
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5878
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.4.0
            Reporter: Sangjin Lee
            Assignee: Sangjin Lee


There are some standard JDK APIs that are not part of the mapreduce.job.classloader.system.classes
property value.

Currently the default value covers only "java.,javax." from the JDK. However, there are other
APIs that are as well-established as these, such as org.w3c.dom and org.xml.sax. In other
similar systems (e.g. OSGi), it is a standard practice to include both of these packages in
the system classes. We should add these to the default values.
