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.
