Yeah, tough choice between security and backwards compatibility.

I will post a patch so that you can examine the list of ciphers I picked.

> 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.
