Sanjay Radia commented on HADOOP-3518:
--------------------------------------
I have taken a look at NIO2.
NIO2's path class interface does not quite match with ours ( Please see my
comments in HADOOP-4952.)
However, the provider interface looks very promising.
We have an opportunity to work with the JSR203 team to see the provider
interface is sufficient to express Hadoop FS.
Alan Bateman, the spec lead would like to work with the Hadoop community to
prototype the Hadoop FS using NIO2's provider interface.
In particular, if we get this done quickly Alan can present the hadoop fs as a
example at his JavaOne talk this year (May/June 2009?)
Any volunteers for this?
> 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.
