Want NIO.2 (JSR 203) file system provider for Hadoop FileSystem
---------------------------------------------------------------

                 Key: HADOOP-3518
                 URL: https://issues.apache.org/jira/browse/HADOOP-3518
             Project: Hadoop Core
          Issue Type: Wish
          Components: fs
            Reporter: Tom White


JSR 203 (aka "NIO.2" or "more NIO") is defining a rich set of classes for interacting with
files and file systems (as well as other NIO enhancements). It is scheduled to be released
as a part of Java 7.

This motivation behind this issue is to see if NIO.2 can be used as an interface to Hadoop's
FileSystem class before NIO.2 is finalized, thus giving Hadoop developers an opportunity to
influence NIO's design (if necessary). Also, learning more about NIO.2 may inform design decisions
for Hadoop filesystems.

The starting point for this work should be the java.nio.file.spi package (http://openjdk.java.net/projects/nio/javadoc/java/nio/file/spi/package-summary.html).
There is an example of a filesystem provider (for ZIP files) linked from the OpenJDK page
for NIO.2: http://openjdk.java.net/projects/nio/. This page also has other useful links, such
as a JavaOne talk, javadoc and source code.
