Apache Spark commented on SPARK-20440: -------------------------------------- User 'vijoshi' has created a pull request for this issue: https://github.com/apache/spark/pull/17731 > Allow SparkR session and context to have delayed binding > -------------------------------------------------------- > > Key: SPARK-20440 > URL: https://issues.apache.org/jira/browse/SPARK-20440 > Project: Spark > Issue Type: Improvement > Components: SparkR > Affects Versions: 2.1.0 > Reporter: Vinayak Joshi > > It would be useful if users could do something like this without first > invoking {{sparkR.session()}}: > {code} > delayedAssign(".sparkRsession", { sparkR.session(..) }, > assign.env=SparkR:::.sparkREnv) > {code} > This would help providers of interactive environments that bootstrap Spark > for their users but the user code need not always include SparkR and so > possibility of lazy semantics for setting up a SparkSession/Context would be > very useful. > Note that SparkR API does not have a single entry object (such as > Scala/Python SparkSession classes) so it's the only env where such lazy setup > is currently difficult to achieve, so doing this enhancement will make it > easier. > The changes required are minor and do not affect the external API or > functionality in any way. I will attach a PR with the changes needed for > consideration shortly. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
