--------------------------------
Summary: Master should not store arbitrarily sized data in
ExecutorInfo
Key: MESOS-3794
URL: https://issues.apache.org/jira/browse/MESOS-3794
Project: Mesos
Issue Type: Bug
Components: master
Reporter: Joseph Wu
Assignee: Joseph Wu
Priority: Critical
>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].
