Steve Loughran commented on HADOOP-3518:
----------------------------------------
[~damiencarol] -hi, I hadn't seen this before, sorry if you felt ignored.
# Moving to NIO can only be good as a drop in for RawLocalFileSystem;
HADOOP-9590 proposed upgrading that, maybe having a RawNioFileSystem would be
safer.
# This would really help Windows. But that also means windows testing. Are you
set up for that? If not, you'll need help
# Testing really matters for filesystems. That's why we have both a filesystem
specification and a large set of FS contract tests. These are all the
foundational tests ... they verify the core API works, though they don't check
things like concurrency, consistency, durability & failure handling ...
> 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.
