----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
These are the log files I got. I just try to kill one task
task_1440006609204_0002_m_000002, this task is just during SCHED phase not
RUN yet. After it's killed, then come to the exception.
The problem maybe due to the task is trying unregister from
TaskAttemptListenerImpl while it's not register witl TaskAttemptListenerImpl
yet.
> kill task before the task is truely runing on a slave node

> Key: MAPREDUCE-6457
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6457
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: applicationmaster, mrv2
> Affects Versions: 2.6.0, 2.7.1
> Environment: regular environment
> Reporter: Wei Chen
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> I happned to find this bug. When I am doing some development based on
> Hadoop-2.6.0. I happend to send to T_KILL signal to one of maptask before
> this task is register to TaskAttemptListener. Because the attempt is not
> assigned with a container yet. It may lead to a lot of errors.
