You must restore oozie-site.xml from your backup to the conf directory on each oozie server and client.

Copy the JDBC jar to libext-customer.

Copy these files to the libext-customer directory

cp /usr/hdp/current/hadoop/lib/hadooplzo*.jar /usr/hdp/current/oozie/libext-customer

cp /usr/share/HDP-oozie/ext-2.2.zip /usr/hdp/current/oozie/libext-customer/

	Note
	If you do not have an LZO JAR file, you must enable LZO compression first. See Install Compression Libraries.

Extract share-lib.

cd /usr/hdp/current/oozie

tar xzvf /usr/hdp/current/oozie/oozie-sharelib.tar.gz

su -l hdfs -c "hdfs dfs -mkdir -p /user/oozie"

su -l hdfs -c "hdfs dfs -copyFromLocal /usr/hdp/current/oozie/share /user/oozie/."

You can expect to see complaints that some files already exist. Delete any exisitng /oozie/share and replace it with the newly-extracted files.

su -l hdfs -c "hdfs dfs -chown oozie:hadoop /user/oozie" su -l hdfs -c "hdfs dfs -chmod -R 755 /user/oozie"

if a previous version of Oozie was created using auto schema creation, run the following SQL query:

insert into oozie_sys (name, data) values ('db.version', '2.5');

As the Oozie user (not root), run the upgrade.

su $OOZIE_USER

/usr/hdp/current/oozie-server/bin/ooziedb.sh upgrade -run

As root, prepare the Oozie WAR file.

sudo su -l oozie -c "/usr/hdp/current/oozie/bin/oozie-setup.sh prepare-war -d /usr/hdp/current/oozie/libext-customer"

Look for console output to indicate success. For example, if you are using MySQL you should see something similar to:

INFO: Adding extension: libext-customer/mysql-connector-java.jar
New Oozie WAR file with added 'JARs' at /var/lib/oozie/oozie-server/webapps/oozie.war 

Add the following property to oozie-log4j.properties:

log4j.appender.oozie.layout.ConversionPattern=%d{ISO8601} %5p %c{1}:%L - SERVER[${oozie.instance.id}] %m%n

where ${oozie.instance.id} is determined by oozie, automatically.

Start Oozie as the Oozie user:

sudo su -l <OOZIE_User> -c "export OOZIE_CATALINA_HOME='usr/lib/bigtop-tomcat'; $OOZIE_CATALINA_HOME/catalina.sh $OOZIE_CATALINA_HOME/setclasspath.sh
/usr/hdp/current/oozie-server/bin/oozied.sh start”

Check processes.

ps -ef | grep -i oozie
