You must export the Sentry policies from CDH cluster to CDP cluster Ranger.
- SSH to the Sentry host of the source cluster.
Copy the file located here to the Sentry host and extract it to a suitable
tar -xvf authz_export.tar.gzLater, a directory named
authzmigratoris created which contains the following files:
Verify the SENTRY_SERVER process path
ps -ef | grep SENTRY_SERVER

files from Sentry-run directory.
cp /var/run/cloudera-scm-agent/process/<process-id>-sentry-SENTRY_SERVER/sentry-site.xml authzmigrator/config/
cp /var/run/cloudera-scm-agent/process/<process-id>-sentry-SENTRY_SERVER/core-site.xml authzmigrator/config/
