SSL version causes Ambari-agent failure #12

Closed WIN32GG closed 5 years ago

WIN32GG commented 5 years ago

After launching a test cluster with

jumbo > create testcluster -t small-full jumbo (testcluster) > start

the ambari-agent logs showed:

ERROR 2019-02-13 17:03:13,563 NetUtil.py:96 - EOF occurred in violation of protocol (_ssl.c:618) ERROR 2019-02-13 17:03:13,563 NetUtil.py:97 - SSLError: Failed to connect. Please check openssl library versions.

and nodes did not appear.

This can be fixed by adding:

[security] force_https_protocol=PROTOCOL_TLSv1_2

in

/etc/ambari-agent/conf/ambari-agent.ini

Thank you @WIN32GG, this is fixed for version 0.5 currently on dev branch ( https://github.com/adaltas/jumbo/blob/dev/jumbo/core/data/jumbo-services/playbooks/roles/ambariagents/tasks/main.yml#L16 )

Closing.

When I add the property [security] force_https_protocol=PROTOCOL_TLSv1_2 in /etc/ambari-agent/conf/ambari-agent.ini I got a another error : Failed to connect to https://ndsc01:8440/ca due to 'module' object has no attribute 'PROTOCOL_TLSv1_2' WARNING 2020-04-25 18:54:47,471 NetUtil.py:124 - Server at https://ndsc01:8440 is not reachable, sleeping for 10 seconds...
