[jira] [Created] (IGNITE-1267) JobStealingCollisionSpi never sends jobs to a node that joined after task was executed

Valentin Kulichenko created IGNITE-1267:
-------------------------------------------

             Summary: JobStealingCollisionSpi never sends jobs to a node that joined after task was executed
                 Key: IGNITE-1267
                 URL: https://issues.apache.org/jira/browse/IGNITE-1267
             Project: Ignite
          Issue Type: Bug
          Components: compute
    Affects Versions: 1.1.4
            Reporter: Valentin Kulichenko
             Fix For: ignite-1.4


Corresponding user thread (contains detailed description of the scenario that doesn't work): http://apache-ignite-users.70518.x6.nabble.com/Dynamic-ComputeTask-distribution-with-new-nodes-td997.html

Essentially, {{JobStealingCollisionSpi}} always skips jobs that are not in task topology (see line 713). Task topology is static and created when task is executed, so newly joined node can't steal jobs. I think it should be able to do this if it satisfies initial cluster group predicate.
