The class `StreamingMultipleProgramsTestBase` allows to reuse the minicluster across several tests. I would suggest to port all existing example tests (Java and Scala) into a single ITCase which extends `StreamingMultipleProgramsTestBase`. This should reduce Flink's build time. > Sync Scala and Java Streaming Examples > -------------------------------------- > > Key: FLINK-3551 > URL: https://issues.apache.org/jira/browse/FLINK-3551 > Project: Flink > Issue Type: Sub-task > Components: Examples > Affects Versions: 1.0.0 > Reporter: Stephan Ewen > Assignee: Lim Chee Hau > > The Scala Examples lack behind the Java Examples -- This message was sent by Atlassian JIRA (v6.3.4#6332)
