[jira] [Created] (MESOS-53) Master should make offers even for
machines with no free memory
Master should make offers even for machines with no free memory
---------------------------------------------------------------
Key: MESOS-53
URL: https://issues.apache.org/jira/browse/MESOS-53
Project: Mesos
Issue Type: Bug
Reporter: Matei Zaharia
Assignee: Matei Zaharia
Priority: Trivial
With Java-based frameworks such as Spark, it's possible that a framework will claim all the memory on a machine for its executor, but will still need to launch multiple tasks as CPUs free up. Right now the master won't make new offers because it waits for at least MIN_MEM=32 MB free memory on the machine. It would be better to lower this to 0 to avoid this unexpected behavior.
