Cloudera provides a pathway for sharing metadata from an Altus Director managed cluster with Cloudera Altus Data Engineering or Altus Data Warehouse clusters. This blog post outlines how to use Altus Director to set up the required infrastructure as well as configuring the CDH components to enable this functionality.
SDX for Cloudera Altus persists both Apache Hive metadata and Apache Sentry data access policies independently from clusters in SDX namespaces. In this way,

Two new strains of malware–XBash and DemonBot–are targeting Apache Hadoop servers for Bitcoin mining and DDOS purposes. This malware is scanning the internet so vigorously for Hadoop clusters that an infection can occur within minutes of an insecure cluster being placed on the open internet. This blog post describes the mechanism this malware uses and offers specific actions to protect your Hadoop-based clusters.
A History of Hadoop Malware
Roughly two years ago there were a spate of attacks against the open source database solution MongoDB,
