> From a comment in [MESOS-3771]:
> Master should not be storing the {{data}} fields from {{ExecutorInfo}}.  We currently [store the entire object|https://github.com/apache/mesos/blob/master/src/master/master.hpp#L262-L271], which means master would be at high risk of OOM-ing if a bunch of executors were started with big {{data}} blobs.
> * Master should scrub out unneeded bloat from {{ExecutorInfo}} before storing it.
> * We can use an alternate internal object, like we do for {{TaskInfo}} vs {{Task}}; see [this|https://github.com/apache/mesos/blob/master/src/messages/messages.proto#L39-L41].
