Subject [jira] [Created] (SPARK-8130) spark.files.useFetchCache should be off by default
Date Fri, 05 Jun 2015 22:11:00 GMT
Josh Rosen created SPARK-8130:
---------------------------------

             Summary: spark.files.useFetchCache should be off by default
                 Key: SPARK-8130
                 URL: https://issues.apache.org/jira/browse/SPARK-8130
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
            Reporter: Josh Rosen
            Priority: Minor


I noticed that {{spark.files.useFetchCache}} is on by default, but I think that we should
turn it off by default since it's unlikely to improve performance for all but a handful of
users and adds some extra IO / complexity (albeit only at executor / app startup).
