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.
