>             Project: Mesos
>          Issue Type: Bug
>            Reporter: Andrei Sekretenko
>            Priority: Major
>
> As currently implemented, on recovery Mesos agent determines that the executor is generated for command task by comparing the executor command with a current path to Mesos executor:
> https://github.com/apache/mesos/blob/1.7.x/src/slave/slave.cpp#L9635
> During upgrade of production cluster we observed this check to break due to the new launcher_dir being different from the one of checkpointed executor.
> This can cause problems of various kind: for example, after such upgrade, Mesos master can begin to treat the checkpointed command executors as subject to resource quota.
