Network Performance Inspector Results Have Low Latency

New Contributor

I installed cloudera normally in the three servers but at the last step were I need to confirm the network performance, in turns out that the network latency is very low. When I checked the inspector command, the error was the following:

/opt/cloudera/cm-agent/lib/python2.7/site-packages/OpenSSL/crypto.py:12: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in the next release.

But when I run the cloudera-scm-agent.log log file, I end up having the next errors:

If someone knows how to fix this issue, would be very relieved and thankful. I have been struggling for a couple of weeks already.

 

Thank you.
