             Summary: Return jar name when jar is uploaded
                 Key: FLINK-5598
                 URL: https://issues.apache.org/jira/browse/FLINK-5598
             Project: Flink
          Issue Type: Improvement
          Components: Web Client
            Reporter: Sendoh


As as a developer I want jar file name is returned when jar is uploaded
Currently it returns nothing, as the code shown:
File newFile = new File(jarDir, UUID.randomUUID() + "_" + filename);
                        if (tempFile.renameTo(newFile)) {
                                // all went well
                                return "{}";
                        }
Ref: 
https://github.com/apache/flink/blob/master/flink-runtime-web/src/main/java/org/apache/flink/runtime/webmonitor/handlers/JarUploadHandler.java#L58

My proposal will be 

reuturn {"fileName": newFile.getName()}

Any suggestion is welcome.
