Damien Carol commented on HADOOP-3518:
--------------------------------------
No sure we are talking about the same thing.
The goal of this JIRA (also what is implemented by
https://github.com/damiencarol/jsr203-hadoop) is to make this works:
Client ==(NIO/JSR203 interface)==> HDFS => Native FS
What you are talking about is that:
Client ==> HDFS ==(NIO)==> Native FS
> 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 Common
> 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.
