Sean Owen updated SPARK-573: ---------------------------- Priority: Minor > Clarify semantics of the parallelized closures > ---------------------------------------------- > > Key: SPARK-573 > URL: https://issues.apache.org/jira/browse/SPARK-573 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: tjhunter > Priority: Minor > > I do not think there is any guideline about which features of scala are > allowed/forbidden in the closure that gets sent to the remote nodes. Two > examples I have are a return statement and updating mutable variables of > singletons. > Ideally, a compiler plugin could give an error at compile time, but a good > error message at run time would be good also. > Are there any other cases that should not be allowed? -- 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
