-------------------------------------------
Summary: Coarse-grained Mesos scheduler should reject offers for
longer period of time when reached max cores
Key: SPARK-13001
URL: https://issues.apache.org/jira/browse/SPARK-13001
Project: Spark
Issue Type: Improvement
Components: Mesos, Scheduler
Affects Versions: 1.6.0, 1.5.2, 1.5.1, 1.5.0
Reporter: Sebastien Rainville
Similar to https://issues.apache.org/jira/browse/SPARK-10471 but for "reached
max cores".
The coarse-grained Mesos scheduler accepts every offer that match the
requirements until it reaches "spark.cores.max", at which point it will reject
every offer. Even though spark will never launch tasks on these offers, mesos
keeps sending the same offers again every 5 seconds making them unavailable for
other frameworks.
Spark should reject those offers for a longer period of time to prevent offer
starvation when running a lot of frameworks.
