Verify Hadoop Encryption

[#1]

Is there a way to verify RPC encryption in a kerberized cluster for HDFS and YARN ports? Running openssl gives me a "connection reset by peer message" and I suspect this might be because of kerberos authentication.

One quick way to check If encrypted RPC is enabled, the following properties in core-site.xml will be set to privacy in core-site.xml

hadoop.rpc.protection=privacy

The other values are 'authentication’ and ‘integrity’

[#3]

@Geoffrey Shelton Okot Is there anyway to test the encryption on the ports? I'd like to have some documented results as opposed to just trusting the settings. I think I have set everything correctly.

@Jason Farbman

Could this be what you are looking for test

Hope I understood you.
