Sean Owen commented on SPARK-5770: ---------------------------------- Yeah I think that's the point, that overwriting an existing JAR won't cause any classes to be reloaded, so, should it be an error? or a warning? > Use addJar() to upload a new jar file to executor, it can't be added to > classloader > ----------------------------------------------------------------------------------- > > Key: SPARK-5770 > URL: https://issues.apache.org/jira/browse/SPARK-5770 > Project: Spark > Issue Type: Bug > Components: Spark Core > Reporter: meiyoula > > First use addJar() to upload a jar to the executor, then change the jar > content and upload it again. We can see the jar file in the local has be > updated, but the classloader still load the old one. The executor log has no > error or exception to point it. > I use spark-shell to test it. And set "spark.files.overwrite" is true. -- 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
