Colin Patrick McCabe commented on HADOOP-6311:
----------------------------------------------
This latest patch is a new approach, based on the ideas we discussed here.
Basically, the idea is to add a set of generic Socket classes that implement
UNIX domain sockets.
This patch contains no code from Android. The advantages over the previous
approaches are:
* The previous approaches didn't create classes which actually inherited from
{{ServerSocket}} and {{Socket}}. This patch does. This means that
{{DomainSockets}} can be used in all of the places where {{InetSockets}} were
previously used (see the HDFS-347 patch for the application.)
* This patch has unit tests.
* We skip implementing a few things that we don't really need, like
credential-passing
* These classes are fully thread-safe.
> Add support for unix domain sockets to JNI libs
