Stop all HDP 2.3.x Services for your scenario:

For non-Ambari managed clusters:
1. Stop all HDP 2.3.x services using the Stopping HDP Services section of the HDP Reference Guide.
For Ambari 1.7.0-managed clusters:
1. Open Ambari Web.
2. Browse to Services.
3. Use Service Actions to stop each service.

For all services, switch the active version to HDP 2.3.4.

On each host in the cluster, use hdp-select to switch all services to the HDP 2.3.4 version:

hdp-select set all <hdp2.3.4 version>

Complete the Stack Upgrade for your scenario:

For non-Ambari managed clusters:

The following components experienced changes to the required workflow. Please take them into account when upgrading your environment:

Component	Link
Atlas	Configuring Atlas with HBase Configuring Atlas in a Kerberized Cluster
Falcon	Configure and Validate Falcon
HBase	Set Up the Configuration Files Configure and Start HBase
Hive	Setting Up the Hive/HCatalog Configuration Files Configure and Start Hive and HCatalog
Hue	Getting Ready to Upgrade Configure and Start Hue
Kafka	Upgrade Kafka
Oozie	Install the Oozie Package
Ranger	Installing Ranger Plug-ins (Optional step 10)
Tez	Enabling Tez for Hive Queries

For Ambari 1.7.0-managed clusters:
Update the repository Base URLs to use the HDP 2.3.4 repositories for HDP and HDP-UTILS:
1. Open Ambari Web.
2. Browse to Admin > Repositories.
3. Edit the Base URLs.

Start all HDP 2.3.4 services, in the following order:

ZooKeeper
su - zookeeper export ZOOCFGDIR=/usr/hdp/current/zookeeper-server/conf ; export ZOOCFG=zoo.cfg; source /usr/hdp/current/zookeeper-server/conf/zookeeper-env.sh ; /usr/hdp/current/zookeeper-server/bin/zkServer.sh start
(HA NameNode upgrade only) ZooKeeper Failover Controller Daemons
/usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh start zkfc
(HA NameNode upgrade only) JournalNodes
su - hdfs /usr/hdp/current/hadoop-hdfs-journalnode/../hadoop/sbin/hadoop-daemon.sh start journalnode
HDFS NameNode(s)
Start the HDFS NameNode(s). Because there is no metadata schema update for this upgrade, start the NameNode(s) in normal mode:
su - hdfs /usr/hdp/current/hadoop-hdfs-namenode/../hadoop/sbin/hadoop-daemon.sh start namenode
Remaining Services
Start the rest of the HDP services. On each host in the cluster, start the services that are relevant to that cluster. To identify the start commands for all services, see "Controlling HDP Services Manually" in the HDP Reference Guide.

You now have an upgraded cluster. Ensure that your workloads run correctly on this upgraded cluster.
