Sandy Ryza updated SPARK-8135: ------------------------------ Summary: Don't load defaults when reconstituting Hadoop Configurations (was: In SerializableWritable, don't load defaults when instantiating Configuration) > Don't load defaults when reconstituting Hadoop Configurations > ------------------------------------------------------------- > > Key: SPARK-8135 > URL: https://issues.apache.org/jira/browse/SPARK-8135 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Sandy Ryza > Assignee: Sandy Ryza > > Calling "new Configuration()" is an expensive operation because it loads any > Hadoop configuration XMLs from disk. > In SerializableWritable, we call new Configuration needlessly when > instantiating an ObjectWritable. The ObjectWritable only needs the > Configuration for its class cache, not for any Hadoop properties that might > be in XML files, so it should be ok to call new Configuration with > loadDefaults = false. -- 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
