Ryan Tao reopened FLINK-9941: ----------------------------- reopen it. > Flush in ScalaCsvOutputFormat before close method > ------------------------------------------------- > > Key: FLINK-9941 > URL: https://issues.apache.org/jira/browse/FLINK-9941 > Project: Flink > Issue Type: Improvement > Components: API / Scala > Affects Versions: 1.5.1 > Reporter: Ryan Tao > Assignee: Jiayi Liao > Priority: Major > Labels: pull-request-available > > Because not every stream's close method will flush, in order to ensure the > stability of continuous integration, we need to manually call flush() before > close(). > I noticed that CsvOutputFormat (Java API) has done this. As follows. > {code:java} > //CsvOutputFormat > public void close() throws IOException { > if (wrt != null) { > this.wrt.flush(); > this.wrt.close(); > } > super.close(); > } > {code} > -- This message was sent by Atlassian JIRA (v7.6.14#76016)
