-------------------------------------

[~aw] How can I fix the shellcheck errors for the multi-line string? Just 
disable SC2140?

> 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.
