Gabor Gevay updated FLINK-3788: ------------------------------- Summary: Programs extending App trait cause problems because of DelayedInit (was: Local variable values are not distributed to job runners) > Programs extending App trait cause problems because of DelayedInit > ------------------------------------------------------------------ > > Key: FLINK-3788 > URL: https://issues.apache.org/jira/browse/FLINK-3788 > Project: Flink > Issue Type: Bug > Components: DataSet API > Affects Versions: 1.0.0, 1.0.1 > Environment: Scala 2.11.8 > Sun JDK 1.8.0_65 or OpenJDK 1.8.0_77 > Fedora 25, 4.6.0-0.rc2.git3.1.fc25.x86_64 > Reporter: Andreas C. Osowski > Attachments: FLINK-3788.tgz > > > Variable values of non-elementary types aren't caught and distributed to job > runners, causing them to remain 'null' and causing NPEs upon access when > running on a cluster. Running locally through `flink-clients` works fine. > Changing parallelism or disabling the closure cleaner don't seem to have any > effect. > Minimal example, also see the attached archive. > {code:java} > case class IntWrapper(a1: Int) > val wrapped = IntWrapper(42) > env.readTextFile("myTextFile.txt").map(line => wrapped.toString).collect > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
