HDP 3.1, Wired Encryption

A Wired Encryption is not only adding the next layer of security, but also the next layer of complexity. Although everything is described in the HortonWorks documentation, it is not easy to extract the practical steps on how to set up the encryption, it took me some time to accomplish it. So I decided to recap my experience and publish several useful scripts and practical procedure.
What is described
  • Self-signed certificates
  • Enable SSL for WebHDFS, MapReduce, Tez, and YARN
Future plans
  • Certificates signed by CA
  • Other HDP services
  • Application connection
Problem to solve
After enabling the encryption, BigSQL LOAD HADOOP command refused working. It is related to the TimeLine service secure connection. Will try to sort it.
