Which framework provides security in Hadoop?

Apache Ranger [30] provides a centralized framework for securing Hadoop. Ranger is associate authorization system that allows/denies access to Hadoop cluster resources (HDFS files, Hive tables, etc.) supported pre-defined Ranger policies to authenticated users.

What is Kerberos authentication in Hadoop?

Kerberos is an authentication protocol which uses “tickets” to allow nodes to identify themselves. … Hadoop can use the Kerberos protocol to ensure that when someone makes a request, they really are who they say they are. This mechanism is used throughout the cluster.

How is security achieved in Hadoop?

The first step in securing an Apache Hadoop cluster is to enable encryption in transit and at rest. Authentication and Kerberos rely on secure communications, so before you even go down the road of enabling authentication and Kerberos you must enable encryption of data-in-transit.
