The [mailing list discussion|http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Discuss-Add-JobListener-hook-in-flink-job-lifecycle-td27370.html] idled for quite some time. I revived it to see whether there is still some support for proceeding here.

> Third party library would like to add some hook when submitting jobs. So it would be nice to have JobListener for flink.
> More details about the motivation:
> The background is that I am working on integrating flink with apache zeppelin notebook. In apache zeppelin notebook, we allow user to run flink scala code or sql. For each piece fo code, I'd like to associate it with its corresponding flink job. So that user can link to flink job ui in zeppelin notebook, also he can cancel this job. Here's one screenshot of my POC, in this screenshot you can see the FLINK JOB link which will link to the flink job ui. That's why I'd like to add hook in flink's job submission, so that I can link each piece of flink code to paragraph (the following screenshot) which is a concept of zeppelin and is a container that host this piece of code.
> Here's the sample code for reference about how I use JobListener in zeppelin.
