Creating and Managing SSL Certificates

Creating and managing SSL certificates: CA, OpenSSL, installing certificates in the Hadoop SSL keystore factory.

Obtain a Certificate from a Trusted Third Party Certification Authority CA
To obtain a certificate signed by a third-party CA, generate and submit a Certificate Signing Request (CSR) for each cluster node.
Create and Set Up an Internal CA OpenSSL
OpenSSL provides tools to allow you to create your own private certificate authority. How to create and set up a CA.
Install Certificates in the Hadoop SSL Keystore Factory (HDFS, MapReduce, and YARN)
HDFS, MapReduce, and YARN use the Hadoop SSL Keystore Factory to manage SSL Certificates. This factory uses a common directory for server keystore and client truststore. The Hadoop SSL Keystore Factory allows you to use CA certificates managed in their own stores.
