Post-upgrade steps on CDP
After you complete the upgrade of HDF, you need to verify or modify properties for NiFi
Registry, NiFi, Ranger, Solr, and Zookeeper, migrate Kafka Ranger policies, and enable security if
you want to use a secure cluster. You also need to set core configuration service, and configure
Enabling security If your previous cluster was secure or if you want to use a secure cluster, you have to enable Kerberos and auto-TLS. Setting core configuration service You need to add core configuration service to your cluster manually. The core configuration service allows you to create clusters without the HDFS service. Starting Zookeeper service You must configure the Zookeeper server hosts to start the Zookeeper service. Configuring NiFi Registry settings Before you first start NiFi Registry, you need to set the database password for NiFi Registry in Cloudera Manager and you need to migrate the NiFi Registry directories. If you have Kerberos enabled and Ranger installed, you also need to configure those for NiFi Registry before the first start. Verifying Ranger configurations You need to verify Ranger configurations before you start using the Ranger service. Configuring Ranger settings You need to configure Ranger settings and execute Ranger actions. Configuring Solr settings You need to configure Solr settings before you start using the Solr service. You also need to start Zookeeper service. Initializing Solr You need to execute Solr actions before you start using the Solr service to ensure that Solr is initialized correctly. Configuring NiFi settings You need to configure NiFi settings after you start NiFi successfully. Configuring YARN settings You need to configure YARN settings before you start using the YARN service. Migrating Kafka Ranger policies After the upgrade of HDF to CFM on CDP, you must configure Kafka-centric clusters that use Ranger. You need to set Kafka Ranger policies. You need to ensure that the Ranger service name property has identical value for both Kafka and Ranger.
