# Finding the Flink web interface
Flink UI

The Application Master that belongs to the Flink application hosts the Flink web interface. It is an alternative way to submit a JAR as a job or to view the current status of other jobs. The Flink web interface is active as long as you have a Flink session running. If you have a long-running YARN job already active, you can follow the instructions in the [Connect to the primary node with SSH](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-connect-master-node-ssh.html) topic in the *Amazon EMR Management Guide* to connect to the YARN ResourceManager. For example, if you've set up an SSH tunnel and have activated a proxy in your browser, you choose the ResourceManager connection under **Connections ** in your EMR cluster details page.

After you find the ResourceManager, select the YARN application that's hosting a Flink session. Choose the link under the **Tracking UI** column.

In the Flink web interface, you can view configuration, submit your own custom JAR as a job, or monitor jobs in progress.
