Yes, I can also access XtreemFS through Hadoop's FSShell and run
yarn/mapreduce jobs

Does one of the Hadoop configuration files contain an entry with the
key "fs.xtreemfs.impl" ?

Hi!
You can reference a Hadoop configuration with a defaultFS entry
via "fs.hdfs.hadoopconf".
Have a look at the configuration reference for details:
http://flink.incubator.apache.org/docs/0.7-incubating/config.html
Let us know if it works for XtreemFS...
Greetings,
Stephan

Thanks, now it works :) It is possible so set a default
filesystem in flink like in Hadoop (with fs.default.name
<http://fs.default.name>)? Currently I always have to set the
complete file URI like xtreemfs://<host>:<port>/file
Best,
Lukas

Hi Lukas,
I see that there is a XtreemFS Hadoop client
(http://www.xtreemfs.org/download.php?t=source). WIth this
pending pull request
https://github.com/apache/flink/pull/268 you can use all
file systems supported by hadoop with Flink (we support the
org.apache.hadoop.FileSystems interface).
The pull request has not been merged yet because of a
failing test, but that should not affect you.
If you want, you can check out the branch of my pull request
git clone https://github.com/rmetzger/flink.git
cd flink
git checkout flink1266
mvn clean install -DskipTests
In the "flink-dist/target/flink-XXX/flink-yarn-XXX/"
directory is the finished built.
Let me know if you need more help or information.
Best,
Robert

Hello,
I like to test flink on YARN with the alternative file
system XtreemFS. Therefore I have to add a jar file to
flink but I found no possibility to do so. How can I do
this? Hadoop works fine with XtreemFS.
Thanks
Lukas
