Subject [jira] [Created] (SPARK-23285) Allow spark.executor.cores to be fractional
Date Wed, 31 Jan 2018 14:24:00 GMT
Anirudh Ramanathan created SPARK-23285:

             Summary: Allow spark.executor.cores to be fractional
                 Key: SPARK-23285
             Project: Spark
          Issue Type: Improvement
          Components: Kubernetes, Scheduler, Spark Submit
    Affects Versions: 2.4.0
            Reporter: Anirudh Ramanathan

There is a strong check for an integral number of cores per executor in [] Given
we're reusing that property in K8s, does it make sense to relax it?


K8s treats CPU as a "compressible resource" and can actually assign millicpus to individual
containers. Also to be noted - spark.driver.cores has no such check in place.
