Svend Vanderveken commented on SPARK-6630: ------------------------------------------ Oh, ok. For the record (and my education...) , could you clarify how does this breaks binary compatibility ? Do you mean that client code written against older version of spark would no longer work on this version? > SparkConf.setIfMissing should only evaluate the assigned value if indeed > missing > -------------------------------------------------------------------------------- > > Key: SPARK-6630 > URL: https://issues.apache.org/jira/browse/SPARK-6630 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 1.3.0 > Reporter: Svend Vanderveken > Priority: Minor > > The method setIfMissing() in SparkConf is currently systematically evaluating > the right hand side of the assignment even if not used. This leads to > unnecessary computation, like in the case of > {code} > conf.setIfMissing("spark.driver.host", Utils.localHostName()) > {code} -- 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
