-------------------------------------
Assignee: Benjamin Mahler
> Command Executors do not have Executor IDs in the master.
> ---------------------------------------------------------
>
> Key: MESOS-527
> URL: https://issues.apache.org/jira/browse/MESOS-527
> Project: Mesos
> Issue Type: Bug
> Reporter: Benjamin Mahler
> Assignee: Benjamin Mahler
>
> The webui is broken for command executors because the master does not know
> the executor ID for the tasks using a command executor. This is because the
> Task protobuf only has the executor_id field, no other field to indicate the
> presence of the command executor.
> It seems the slave also doesn't set the Task.executor_id for command
> executors, thus relying on it being optionally set in executorTerminated() to
> determine whether the task used a command executor.
> This all seems pretty messy, a few things to consider:
> 1) Should we simply always set the Task.executor_id for these tasks? The
> master could do so currently, but there would be an implicit contract that
> the slave and master both use the task id as the executor id.
> 2) We can add a boolean is_command_executor to Task, so that both the master
> and slave can set the field, and the slave can use the boolean in
> executorTerminated() to determine whether the task used a command executor.
> 3) Alternatively, we can add a /frameworks/FID/tasks/TID url format for the
> broken links on the master webui, so that we can search for the task in the
> slave state to locate its executor.
