------------------------------------
hi,
I'm Duncan, and i'm approaching to vfs for the first time.
i've tried a simple program to use this vfs-hdfs libraries, but I don't
understand what to do to make them work.
If I've a simple project, with the vfs2 and the pentaho-hdfs-vfs-1.0 libraries
added in my libraries' project: what I've to do to make them work?
If I do nothing it give me this error:
org.apache.commons.vfs2.FileSystemException: Badly formed URI
"hdfs://localhost:9000/user/giuseppe/input/timestamp.png"
at
org.apache.commons.vfs2.provider.url.UrlFileProvider.findFile(UrlFileProvider.java:91)
[...]
java.net.MalformedURLException: unknown protocol: hdfs
thanks in advace :)
> Implement an Apache Commons VFS Driver for HDFS
> -----------------------------------------------
>
> Key: HDFS-1213
> URL: https://issues.apache.org/jira/browse/HDFS-1213
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: hdfs client
> Reporter: Michael D'Amour
> Attachments: HADOOP-HDFS-Apache-VFS.patch,
> pentaho-hdfs-vfs-TRUNK-SNAPSHOT-sources.tar.gz,
> pentaho-hdfs-vfs-TRUNK-SNAPSHOT.jar

>
> We have an open source ETL tool (Kettle) which uses VFS for many input/output
> steps/jobs. We would like to be able to read/write HDFS from Kettle using
> VFS.
>
> I haven't been able to find anything out there other than "it would be nice."
>
> I had some time a few weeks ago to begin writing a VFS driver for HDFS and we
> (Pentaho) would like to be able to contribute this driver. I believe it
> supports all the major file/folder operations and I have written unit tests
> for all of these operations. The code is currently checked into an open
> Pentaho SVN repository under the Apache 2.0 license. There are some current
> limitations, such as a lack of authentication (kerberos), which appears to be
> coming in 0.22.0, however, the driver supports username/password, but I just
> can't use them yet.
> I will be attaching the code for the driver once the case is created. The
> project does not modify existing hadoop/hdfs source.
