Subject [jira] [Created] (MAPREDUCE-5802) Provide an inclusion list mapreduce.job.classloader.job.classes for the class loading isolation
Date Wed, 19 Mar 2014 00:10:43 GMT
Gera Shegalov created MAPREDUCE-5802:
----------------------------------------

             Summary: Provide an inclusion list mapreduce.job.classloader.job.classes for
the class loading isolation
                 Key: MAPREDUCE-5802
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5802
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Gera Shegalov


MAPREDUCE-1700  introduced a way to isolate job-suplied classes in an Application Classloader.
 mapreduce.job.classloader.system.classes is a way to provide an exclusion list for this class
loader. Sometimes it's much easier to express what to include. For this purpose, we propose
an inclusion list. mapreduce.job.classloader.job.classes.  The semantics would be use the
exclusion list unless the inclusion list is specified to determine what classes should be
loaded in the app class loader.
