Thomas Tauber-Marshall commented on IMPALA-7519:
------------------------------------------------

The motivation is security primarily. There's an Impala user who has business 
requirements for using this type of cipher.

Fwiw, we already support this in the krpc stack, this would just be to extend 
the same support to the thrift stack.

I have a review out here: https://gerrit.cloudera.org/#/c/11376/

> Thrift's SSLSocketFactory class does not support setting ciphers that use 
> ecdh. We already override this class for others reasons, it would be 
> straightforward to add the necessary openssl calls to enable this.
