Migrating HDFS native permissions to CDP

If you have HDFS native permissions in your CDH or HDP clusters, you learn how to convert the native permissions into Ranger policy format and import the policies to CDP. You can choose to ignore this migration process if you do not have any HDFS native native permissions.

Migrating HDFS native permissions from CDH or HDP to CDP involves a combination of Extract > Convert > Transform > Import operations.

The HDFS native permissions are first extracted as a file in a specific format, which are then converted and transformed into Ranger AWS S3 policies using the Ranger policy migration utility. The transformed Ranger policies are finally imported into CDP using the authzmigrator tool.
