To enable Audit to HDFS for a plugin do the below

1. Depending upon Keberos or non-kerberos mode, one of the scripts from here need to be run: https://github.com/apache/incubator-ranger/tree/master/security-admin/contrib/audit_hdfs_folders 
2. Set XAAUDIT.HDFS.ENABLE = true for respective component plugin in the install.properties file which may be found in /usr/local/ranger­<component>­plugin/ directory.
3. Configure NameNode host in the XAAUDIT.HDFS.HDFS_DIR.
4. Create a policy in HDFS service from Ranger Admin for individual component users (hive/hbase/knox/storm/yarn/kafka/kms) to give READ+ WRITE permission for the particular audit folder. i.e for enabling Hive component to log Audits to HDFS , we need to create a policy for hiveuser with READ+ WRITE permissions to respective audit directory
5. Audit to HDFS caches logs in local directory, which can be specified in XAAUDIT.HDFS.LOCAL_BUFFER_DIRECTORY ( this can be like ‘/var/log/<component>/**), which is the path where audit is stored temporarily, likewise for archived logs we need to update XAAUDIT.HDFS.LOCAL_ARCHIVE_DIRECTORY value ( this can be like ‘/var/log/<component>/**), before enabling the plugin for the component.
