-----------------------------------------

             Summary: Detecting whether executor is generated for command task should work when the launcher_dir changes
                 Key: MESOS-10084
                 URL: https://issues.apache.org/jira/browse/MESOS-10084
             Project: Mesos
          Issue Type: Bug
            Reporter: Andrei Sekretenko


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.
