Categories: Cloudera Navigator Platform Security & Cybersecurity YARN

Learn how Cloudera Navigator Encrypt bring data security to YARN containers.

With the introduction of transparent data encryption in HDFS, we are now a big step closer toward a secure platform in the Apache Hadoop world. However, there are still gaps in the platform, including how YARN and its applications manage their cache. In this post, I’ll explain how Cloudera Navigator Encrypt fills that particular gap.

Use Case

When a YARN application runs in a cluster it can sometimes spill data to the hard disk,
