Ted Yu commented on SPARK-1714:
-------------------------------
allocatedHostToContainersMap.synchronized is absent for the following operation
in runAllocatedContainers():
{code}
val containerSet =
allocatedHostToContainersMap.getOrElseUpdate(executorHostname,
new HashSet[ContainerId])
containerSet += containerId
allocatedContainerToHostMap.put(containerId, executorHostname)
{code}
Is that intentional ?
