      Complete these pre-upgrade steps for each component in the Ecosystem Pack that you want to upgrade.
    - Upgrading the Ecosystem Pack With the Installer
      If the cluster that you want to upgrade was installed using the Installer, you can use the Installer to upgrade the Ecosystem Pack (EEP).
    - Upgrading the Ecosystem Pack Without the Installer
      After you upgrade core without using the Installer, you need to upgrade ecosystem components with manual steps. First, verify that your repository is configured to use an Ecosystem Pack (EEP) that is supported by your cluster version. Then, upgrade each component manually.

Upgrading Flink

This section describes how to upgrade Flink.

If you want to save any running job and use it in future, stop the job and create a savepoint:
```
/opt/mapr/flink/flink-<version>/bin/flink stop <job_id> --savepointPath <savepoints_directory>
```
Save the given in the output savepoint path (you may want to use after reinstallation).
To stop any running Flink cluster (YARN application), run the following command:
```
echo "stop" | /opt/mapr/flink/flink-<version>/bin/yarn-session.sh -id <application_id>
```
Run the applicable commands as the cluster admin (typically the mapr user), to upgrade through CLI:

Ubuntu

apt upgrade mapr-flink

RHEL

yum update mapr-flink

Start the Flink cluster:

/opt/mapr/flink/flink-<version>/bin/yarn-session.sh --detached

Resume your job from the savepoint that was saved in Step 1:

/opt/mapr/flink/flink-<version>/bin/flink run -s <given_savepoint_path> -d t <job_jar>
