Dian Fu updated HADOOP-10768: ----------------------------- Attachment: HADOOP-10768.002.patch > Optimize Hadoop RPC encryption performance > ------------------------------------------ > > Key: HADOOP-10768 > URL: https://issues.apache.org/jira/browse/HADOOP-10768 > Project: Hadoop Common > Issue Type: Improvement > Components: performance, security > Affects Versions: 3.0.0 > Reporter: Yi Liu > Assignee: Dian Fu > Attachments: HADOOP-10768.001.patch, HADOOP-10768.002.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
