Final answer:
An authentication mechanism in Hortonworks Data Platform refers to the method used to verify the identity of a user or system accessing the platform. The available mechanisms in HDP include Kerberos, OAuth, and LDAP.
Step-by-step explanation:
An authentication mechanism is a method used to verify the identity of a user or system trying to access a system or service. In the Hortonworks Data Platform (HDP), there are several authentication mechanisms available. These include:
- Kerberos: Kerberos is a network authentication protocol that uses encryption keys to verify the identity of users and services in a network environment.
- OAuth: OAuth is an open standard for authorization that allows users to grant access to their information from one service to another without sharing their passwords.
- LDAP: LDAP stands for Lightweight Directory Access Protocol, which is a protocol for accessing and maintaining directory information. It can be used for authentication by verifying user credentials against a directory server.
SSL (Secure Sockets Layer) is not typically considered an authentication mechanism, but rather a security protocol that provides secure communication over a network.
