[jira] [Commented] (FLINK-1722) Streaming not respecting FinalizeOnMaster for output formats

["Robert Metzger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-1722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16071226#comment-16071226 ] 

Robert Metzger commented on FLINK-1722:
---------------------------------------

I think we should add a check to the code. Silently ignoring the interface in the streaming api is not a good system behavior

> The Hadoop output formats execute a process in the end to move the produced files from a temp directory to the final location.
> The batch API is annotating output formats that execute something in the end with the {{FinalizeOnMaster}} interface.
> The streaming component is not respecting this interface. Hence, HadoopOutputFormats aren't writing their final data into the desired destination.
