Post-Upgrade Steps for Hadoop and YARN

Complete the following steps after you upgrade Hadoop and YARN with or without the Installer.

About this task

On each node, run configure.sh with the -R option. Include the -TL option if the timeline server is installed on the cluster. For example:
```
configure.sh -R -HS <hostname> -TL <hostname>
```
Optional: Transfer any custom configuration settings into the new default files in the configuration directory:
New configuration directory: /opt/mapr/hadoop/hadoop-<version>/etc/hadoop/
Backup configuration directory: /opt/mapr/hadoop/hadoop-<timestampversion>/etc/hadoop/

In the backup configuration directory, <timestampversion> is the version from packages that were installed before the upgrade. For example: 2.7.4.100.202101211026.
