[jira] [Created] (UIMA-4106) DUCC RM Use getMemFree instead of getMemTotal for share calculations

Jim Challenger created UIMA-4106:
------------------------------------

             Summary: DUCC RM Use getMemFree instead of getMemTotal for share calculations
                 Key: UIMA-4106
                 URL: https://issues.apache.org/jira/browse/UIMA-4106
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
    Affects Versions: 1.1.0-Ducc
            Reporter: Jim Challenger


getMemFree() turns out not to be the FreeMemory from /proc but instead is TotalMemory - sum(processes owned by (uid<500)).  This switch allows RM to calculate available memory without overcommitting into mostly-stable system-owned processes.
