[~lindongdong] you can check the previous CI results, if we define an unused
method, CI will be unhappy. and I still don't know why there is a compatible
issue, the method you said will not be used any place, can you please explain
more ?
The modification of
[OpensslSecureRandom.c|https://github.com/apache/hadoop/pull/2211/files#diff-3ee504e8c2a27c840c39c4496a27cc02]
I think is to make OpenSSL interface to support SM4, such as check of the
OpenSSL version(SM4 feature require OpenSSL>=1.1.1).

> SM4 (formerly SMS4)is a block cipher used in the Chinese National Standard
> for Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure).
> SM4 was a cipher proposed to for the IEEE 802.11i standard, but has so far
> been rejected by ISO. One of the reasons for the rejection has been
> opposition to the WAPI fast-track proposal by the IEEE. please see:
> [https://en.wikipedia.org/wiki/SM4_(cipher)]

> *Use sm4 on hdfs as follows:*
> 1.Configure Hadoop KMS
> 2.test HDFS sm4
> hadoop key create key1 -cipher 'SM4/CTR/NoPadding'
> hdfs dfs -mkdir /benchmarks
> hdfs crypto -createZone -keyName key1 -path /benchmarks
> *requires:*
> 1.openssl version >=1.1.1
