> Key: MESOS-3794
> URL: https://issues.apache.org/jira/browse/MESOS-3794
> Project: Mesos
> Issue Type: Bug
> Components: master
> Reporter: Joseph Wu
> Priority: Critical
> Labels: mesosphere
>
> 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].
