5. Upgrade Oozie - Hortonworks Data Platform

Execute the following command on the Oozie server and client machines:

For RHEL/CentOS:

yum upgrade oozie* oozie-client*

For SLES:

zypper remove oozie
zypper install oozie oozie-client

	Important
	When removing and installing packages, rename those files the `/conf` directory that have `.rpmsave` extension to original to retain the customized configs. Alternatively, you can also use the configuration files (under the `/conf` directory) you backed up before upgrading.

Start Oozie.

 sudo su -l $OOZIE_USER -c "cd $OOZIE_LOG_DIR/log; /usr/lib/oozie/bin/oozie-start.sh"

where

$OOZIE_USER is the Oozie Service user. For example, oozie.
$OOZIE_LOG_DIR is the directory where Oozie log files are stored (for example: /var/log/oozie).

Validate Oozie.

oozie admin -$OOZIE_USER http://$fully.qualified.domain.name_for_Oozie_hostmachine:11000/oozie -status

You should see the following output:

System mode: NORMAL
