-----------------------------------------

             Summary: Per-job Yarn clusters: include user jar in system class loader
                 Key: FLINK-4913
                 URL: https://issues.apache.org/jira/browse/FLINK-4913
             Project: Flink
          Issue Type: Improvement
          Components: Client, YARN Client
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels
             Fix For: 1.2.0, 1.1.4


Including the jar directly in the system classloader avoids loading it for every instantiation of the ExecutionGraph and every Task execution. Note, this is only possible for per-job clusters (i.e. Yarn/Mesos).
