Review request for mesos, Benjamin Hindman, Eric Biederman, Ian Downes, David
Mackey, and Vinod Kone.
Bugs: MESOS-662
https://issues.apache.org/jira/browse/MESOS-662
Repository: mesos-git
Description
-------
This adds onto tdmackey's patch here: https://reviews.apache.org/r/14024/
In addition to having the OOM killer enabled, this adds memory threshold
notifications in order to induce our own OOMs upon reaching the requested
memory limit. This allows us to capture the relevant memory.stat information at
the time of the OOM event for the majority of OOMs.
When a process is allocating quickly enough to hit the hard limit, this will
still behave correctly by allowing the OOM killer to correct the OOM. In this
case, we will report memory information that excludes the offending process,
but that's the best we can do for now.
