Hi, [~jzhuge]

The patch LGTM overall. +1. 

One thing that might be worth to do is adding a warning message to the script 
when HttpFS uses old SSL clients.  We can do it in a follow up JIRA though. 

Thanks for the patch!

> 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.
