Sean Owen commented on SPARK-761: --------------------------------- Yes, but, what would you check? The goal is not to forbid mismatched versions from talking -- we don't even have a version to check anyway -- but somehow detect when an error is due to this and print something nicer. I don't think it's possible in general; might be reliably possible in a few situations. > Print a nicer error message when incompatible Spark binaries try to talk > ------------------------------------------------------------------------ > > Key: SPARK-761 > URL: https://issues.apache.org/jira/browse/SPARK-761 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Reporter: Matei Zaharia > Priority: Minor > Labels: starter > > As a starter task, it would be good to audit the current behavior for > different client <-> server pairs with respect to how exceptions occur. -- 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
