Why architecture matters here

Authorization fails on plugin drift + missing audit. Architecture matters because policies + plugins + audit compose.

The architecture: every piece explained

The top strip is control. Ranger admin. Policies. Tags. Plugins.

The middle row is enforcement + audit. Audit. Solr / HDFS sink. Kerberos. Row/column masking.

The lower rows are ops. Deny + allow rules. Metrics. Ops — policy lifecycle + rotation.

End-to-end flow

End-to-end: user submits Hive query. Kerberos authenticates. Hive plugin queries Ranger policy cache. Tag-based rule applies masking. Audit event lands in Solr.
