             Summary: SVM - Regression lambda handling on GP
                 Key: MADLIB-1143
                 URL: https://issues.apache.org/jira/browse/MADLIB-1143
             Project: Apache MADlib
          Issue Type: Bug
          Components: Module: Support Vector Machines
            Reporter: Cooper Sloan


Lambda parameter is not stored in the state, rather it is stored as a static field within the L2 template class, and set during the transition function.  On greenplum, this static field cannot be read from the L2 class during the final function if the master is on a different process from the segment.

The fix is simply to include lambda as part of the state, and read it in the final function.
