--------------------------------
Summary: Executor killed when multiple persistent volumes specify
same container_path
Key: MESOS-4017
URL: https://issues.apache.org/jira/browse/MESOS-4017
Project: Mesos
Issue Type: Bug
Affects Versions: 0.25.0
Reporter: Greg Mann
[~gabriel.hartm...@gmail.com] recently noticed that his custom executor was
getting killed by master when multiple tasks attempt to use persistent volumes
with the same {{container_path}}. A {{CREATE}} operation that created two
persistent volumes with the same {{container_path}} succeeded, and a subsequent
offer included those persistent volumes. Then tasks were launched on a single
executor that used these volumes, and at that point the master killed the
executor. Better behavior might be for the first task to launch successfully,
with the second task returning {{TASK_FAILED}} with an appropriate reason and
message.
