Subject [jira] [Created] (AURORA-1046) Memory leak in CachedClusterState
Date Thu, 22 Jan 2015 01:03:59 GMT
Maxim Khutornenko created AURORA-1046:

             Summary: Memory leak in CachedClusterState
                 Key: AURORA-1046
             Project: Aurora
          Issue Type: Bug
          Components: Scheduler
            Reporter: Maxim Khutornenko

This happens due to StateManager.assignTask() implementation [1] firing a TaskStateChange
event before updating the assignedTask slaveId and slaveHost fields. As a result, all ASSIGNED
preemption victims fall under a null key [2] thus leaking memory over time. 

As a side effect, it makes it impossible for the preemptor to preempt tasks in ASSIGNED state.
