Migrating NiFi Registry directories

You must create a working directory to start the NiFi Registry service. The directory is the place where NiFi Registry stores existing buckets, configuration files, database files, and so on.

  • You have set the NiFi Registry database password in Cloudera Manager.
  • You have configured Ranger for NiFi Registry if your cluster contains Ranger.
  1. Create a working directory for NiFi Registry and copy the content from the old directory: 
    mkdir /var/lib/nifiregistry
cp  -R /var/lib/nifi-registry/* /var/lib/nifiregistry
chmod 755 /var/lib/nifiregistry
chown -R nifiregistry:nifiregistry /var/lib/nifiregistry
  2. Start the NiFi Registry service.
