Andrew Ash commented on SPARK-2585: ----------------------------------- I also vote for "correct by default" and there are various potentially dangerous knobs you can turn to squeeze out more performance at risk if you care to. Note that the {{new JobConf()}} constructor loads defaults out of the Hadoop config files (I think {{core-site.xml}} and {{hdfs-site.xml}}) and you can disable that with the {{JobConf(false)}} constructor. Not sure if we need the local config files per server or if all the config options come solely from the driver's {{JobConf}} when instantiated. > Remove special handling of Hadoop JobConf > ----------------------------------------- > > Key: SPARK-2585 > URL: https://issues.apache.org/jira/browse/SPARK-2585 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Patrick Wendell > Assignee: Josh Rosen > Priority: Critical > > This is a follow up to SPARK-2521 and should close SPARK-2546 (provided the > implementation does not use shared conf objects). We no longer need to > specially broadcast the Hadoop configuration since we are broadcasting RDD > data anyways. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
