---------------------------------
Summary: Tasks mistakenly marked as FAILED due to race b/w
sendExecutorTerminatedStatusUpdate() and _statusUpdate()
Key: MESOS-6026
URL: https://issues.apache.org/jira/browse/MESOS-6026
Project: Mesos
Issue Type: Bug
Components: slave
Reporter: Kapil Arya
Due to a race between sendExecutorTerminatedStatusUpdate() and
_statusUpdate() that happens when the task has just finished and the
executor is exiting.
Here is an example of slave log messages:
{code}

{code}
As can be noticed, the task is marked as TASK_FAILED after the executor has
exited.
