Post-migration steps on CDP
After you complete the migration of HDF, you need to verify or modify properties for
NiFi Registry, NiFi, Ranger, Solr, and Zookeeper, and enable security if you want to use a
secure cluster.
Enable security If your previous cluster was secure or if you want to use a secure cluster, you have to enable Kerberos and auto-TLS.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.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.
