             Summary: DUCC Setup. Adjust defaults to support 8GB test rigs.
                 Key: UIMA-2996
                 URL: https://issues.apache.org/jira/browse/UIMA-2996
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger
             Fix For: 1.0-Ducc

The current default setup uses a 4GB scheduling quantum.  On 8GB machines, this will likely
result in only 1 share being available because the hardware reports slightly less than true
memory.  As well, the setup should account for a single node, and thus not set a jobdriver

The default quantum should probably be 2GB in order to accommodate 8GB test and initial setups.

This affects ducc.properties, ducc.classes, the test jobs, and documentation.
