Wei-Chiu Chuang updated HADOOP-12886:
-------------------------------------
Attachment: HADOOP-12886.004.patch
Thanks again [~zhz] for reviewing it.
In addition to addressing your comments, I added additional code to deal with
the corner case where the exclude list string is empty, and that it should
initializes an empty list, instead of initializing a one element list. This
actually doesn't change anything though.
> Exclude weak ciphers in SSLFactory through ssl-server.xml

> HADOOP-12668 added support to exclude weak ciphers in HttpServer2, which is
> good for name nodes. But data node web UI is based on Netty, which uses
> SSLFactory and does not read ssl-server.xml to exclude the ciphers.
> We should also add the same support for Netty for consistency.
> I will attach a full patch later.
