Required jars:

• log4j2 (comes with flink)
• log4j2-logstash-layout (https://github.com/vy/log4j2-logstash-layout)
• jackson-core (my version is 2.12.0)
• jackson-databind (my version is 2.12.0)
• jackson-annotations (my version is 2.12.0)

Note: It seems that since Log4j 2.14.0, we do not need to add jackson dependencies according to log4j documentation. However I need to stick with log4j2 version comes with Flink for now, so I have not tested it yet.
