      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.

    Description

      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.
