Error with web service call

Hi,

I have built a workflow for clustering. I’d like to execute my workflow and show some files that the ws returned me back. I can execute with out problems my workflow in my local machine, but when I want to execute through my ws I got the following error message:

Warning:   StandardWrapperValve[edu.ucuenca.kodar.webservice.ApplicationConfig]: Servlet.service() for servlet edu.ucuenca.kodar.webservice.ApplicationConfig threw exception
java.lang.NoClassDefFoundError: Could not initialize class org.apache.hadoop.conf.Configuration


I don’t why it is happening. I thought It was for the classpath, but I added to my client ws all the dependencies of mahout. The error sills. Could anyone help me?

Cheers.

Hi, 

After all I solved my problem. It was because I had multiple bindings and I don’t know why the error is launched just when the web service is executed. 

Now I have the following error:

java.lang.UnsupportedOperationException: Not implemented by the DistributedFileSystem FileSystem implementation

I thought it was for the configuration. I tried to run with the API of hadoop and with a native cluster conf.set("fs.defaultFS", "hdfs://172.16.147.7:54310”). I just have problems when I try to execute through my ws. The difference between my configurations are the class loaders (LauncherClassLoader for my app and WebAppClassLoader for my ws). I don’t know why it s happening.

Cheers.
