Review request for Ambari, Dmytro Sen, Mahadev Konar, and Yusaku Sako.
Bugs: AMBARI-14778
https://issues.apache.org/jira/browse/AMBARI-14778
Repository: ambari
Description
-------
The Ambari Server (built-in) CA should use {{SHA265}} as default message digest
algorithm rather than the no longer trusted {{MD5}} and {{SHA1}} digest
algorithms.
To do this, change the following line (in both the unix and windows version of
the file):
#ambari-server/conf/.../ca.config#
```
default_md = md5
```
to
```
default_md = sha256
```
Note: This directly affects 2-way SSL between Ambari server and the agents due
to security constraints in newer JVMs, like
```
openjdk version "1.8.0_71"
OpenJDK Runtime Environment (build 1.8.0_71-b15)
OpenJDK 64-Bit Server VM (build 25.71-b15, mixed mode)
```
The following error in the ambari-agent log may indicate that the agent's SSL
certificate is signed using MD5:
```

```
The following error in the ambari-server log (when logging DEBUG messages)
indicates that the agent's SSL certificate is signed using MD5, which is not
supported by the underling JVM:

Manually tested with Oracld JVM 1.7 and 1.8 (with and without JCE installed).
Also tested with OpenJDK 1.8
No unit tests were updated.
Thanks,
