Subject [jira] [Commented] (HADOOP-6311) Add support for unix domain sockets to JNI libs

Colin Patrick McCabe commented on HADOOP-6311:

With regard to security: after further reflection, I think we will need to ask system administrators
establish secure directories to hold the UNIX domain sockets.  In practice, this means a directory
owned by hdfs, where neither it nor any of its parent directories are vulnerable to attack.

bq. ... my question is more this: let's assume that unix sockets for the data path are 3x
as fast as local TCP sockets. If that's the case, then do we still get a big benefit from
Oh, I misinterpreted.  You were talking about using UNIX domain instead of TCP for data traffic.
 Yeah, it could be interesting.  It's a time-honored way to get better performance on UNIXes.
 I'll do some tests if I can get the UNIX domain sockets to implement the "standard" interface
(and if the resulting combination actually works.)  I think there is a good chance that it
