Yi Liu commented on HADOOP-10693:
---------------------------------
Thanks [~tucu00], at runtime, we had already checked whether the loaded openssl
library supports AES-CTR, if not, will cause
{{OpensslCipher.isNativeCodeLoaded()}} false.
Now that snippet of cmake script makes sure correct Openssl version is chosen
for compiling.

> In HADOOP-10603, we have an implementation of AES-CTR CryptoCodec using Java
> JCE provider.
> To get high performance, the configured JCE provider should utilize native
> code and AES-NI, but in JDK6,7 the Java embedded provider doesn't support it.
>
> Considering not all hadoop user will use the provider like Diceros or able to
> get signed certificate from oracle to develop a custom provider, so this JIRA
> will have an implementation of AES-CTR CryptoCodec using JNI to OpenSSL
> directly.
