how to secured zookeeper - encrypt communication

[#1]

hi all

we can see the following zookeeper secured , / encrypt communication articles

https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_administration/content/security-configur...

https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_administration/content/encryption.html

https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.1.1/bk_administration/content/encrypt-config_to...

since the articles are talks about HDP 3.1 version

I not convinced this feature is also support the hdp version - 2.6.4

so can we encrypt / decryption zookeeper on HDP - 2.6.4 ?

Hi @Michael Bronson

By default network communication of ZooKeeper isn’t encrypted. However, each user and service can leverage the SSL feature and/or custom authentication implementation in order to use ZooKeeper in secure mode. Kindly refer the below link.

This feature is added from Zookeeper version 3.5.1 and so on.

Unfortunately the HDP version (which is HDP 2.6.4) includes the Zookeeper version "Apache ZooKeeper 3.4.6" so this feature is not available in HDP yet.

Please accept this answer if you found it helpful.
