Nicholas Chammas commented on SPARK-4924: ----------------------------------------- [~vanzin] - How does this proposal affect, if at all, someone's ability to write a pure Python application that remotely launches a Spark application? > Factor out code to launch Spark applications into a separate library > -------------------------------------------------------------------- > > Key: SPARK-4924 > URL: https://issues.apache.org/jira/browse/SPARK-4924 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Marcelo Vanzin > Attachments: spark-launcher.txt > > > One of the questions we run into rather commonly is "how to start a Spark > application from my Java/Scala program?". There currently isn't a good answer > to that: > - Instantiating SparkContext has limitations (e.g., you can only have one > active context at the moment, plus you lose the ability to submit apps in > cluster mode) > - Calling SparkSubmit directly is doable but you lose a lot of the logic > handled by the shell scripts > - Calling the shell script directly is doable, but sort of ugly from an API > point of view. > I think it would be nice to have a small library that handles that for users. > On top of that, this library could be used by Spark itself to replace a lot > of the code in the current shell scripts, which have a lot of duplication. -- 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
