Wei-Chiu Chuang updated HADOOP-10768:
-------------------------------------
Release Note:
This improvement leverages AES-NI hardware acceleration to optimize Hadoop RPC
performance.
To enable it, adding the following configuration in core-site.xml
<property>
<name>hadoop.rpc.security.crypto.cipher.suites</name>
<value>AES/CTR/NoPadding</value>
</property>
Optionally, set key bit length (default 128) via configuration key
hadoop.rpc.security.crypto.cipher.key.bitlength in core-site.xml.

> Hadoop RPC encryption is enabled by setting {{hadoop.rpc.protection}} to
> "privacy". It utilized SASL {{GSSAPI}} and {{DIGEST-MD5}} mechanisms for
> secure authentication and data protection. Even {{GSSAPI}} supports using
> AES, but without AES-NI support by default, so the encryption is slow and
> will become bottleneck.
> After discuss with [~atm], [~tucu00] and [~umamaheswararao], we can do the
> same optimization as in HDFS-6606. Use AES-NI with more than *20x* speedup.
> On the other hand, RPC message is small, but RPC is frequent and there may be
> lots of RPC calls in one connection, we needs to setup benchmark to see real
> improvement and then make a trade-off.
