Michael Gummelt created SPARK-19373:
---------------------------------------
Summary: Mesos implementation of
spark.scheduler.minRegisteredResourcesRatio looks at acquired cores rather than
registerd cores
Key: SPARK-19373
URL: https://issues.apache.org/jira/browse/SPARK-19373
Project: Spark
Issue Type: Bug
Components: Mesos
Affects Versions: 2.1.0
Reporter: Michael Gummelt
We're currently using `totalCoresAcquired` to account for registered resources,
which is incorrect. That variable measures the number of cores the scheduler
has accepted. We should be using `totalCoreCount` like the other schedulers do.
Fixing this is important for locality, since users often want to wait for all
executors to come up before scheduling tasks to ensure they get a node-local
placement.
