> In AURORA-1076 it was discovered that if an ExecutorInfo was changed such
> that a previously unset optional field with a default value was changed to
> have the field set with the default value, it would be rejected as not
> compatible.
> For example if we have an ExecutorInfo with a CommandInfo with the {{shell}}
> attribute unset and then we change the CommandInfo to set the {{shell}}
> attribute to true Mesos will reject the task with:
> {noformat}
> I0130 21:50:05.373389 50869 master.cpp:3441] Sending status update TASK_LOST
> (UUID: 82ef615c-0d59-4427-95d5-80cf0e52b3fc) for task
> system-gc-c89c0c05-200c-462e-958a-ecd7b9a76831 of framework
> 201103282247-0000000019-0000 'Task has invalid ExecutorInfo (existing
> ExecutorInfo with same ExecutorID is not compatible).
> {noformat}
> This is not intuitive because the default value of the {{shell}} attribute is
> true. There should be no difference between not setting an optional field
> with a default value and setting that field to the default value.
