Edward J. Yoon commented on HAMA-590:
-------------------------------------
I don't remember exactly but, there was NullPointerException at getTaskToRun()
method. I guess, it's a problem of graph partition logic.
{code}
// Failed in attempt to get data locality or there was no input split.
if (selectedGroom == null) {
Iterator<String> groomIter = grooms.keySet().iterator();
while (groomIter.hasNext()) {
GroomServerStatus groom = grooms.get(groomIter.next());
Integer taskInGroom = tasksInGroomMap.get(groom);
taskInGroom = (taskInGroom == null) ? 0 : taskInGroom;
if (taskInGroom < groom.getMaxTasks()) {
selectedGroom = groom;
t = new BSPTask(jobId, jobFile, taskid, partition, splitClass, split);
activeTasks.put(taskid, groom.getGroomName());
}
}
{code}
