John Zhuge commented on HADOOP-14083:
-------------------------------------
bq. are those KMS_SILENT changes related here?
Just random enhancement I threw in
bq. how is the catalina-default.properties file generated / written? I'm not
familiar with tomcat enough to review that file. Any links appreciated.
I generated the file {{catalina-default.properties}} based on the
{{catalina.properties}} automatically generated by Tomcat if it is missing.
Without the default properties, Tomcat would not accept the file with only
custom properties.

> HADOOP-13812 upgraded Tomcat to 6.0.48 which filters weak ciphers. Old SSL
> clients such as curl stop working. The symptom is {{NSS error -12286}} when
> running {{curl -v}}.
> Instead of forcing the SSL clients to upgrade, we can configure Tomcat to
> explicitly allow enough weak ciphers so that old SSL clients can work.
