>          Issue Type: Bug

> I am writing an application in c++, which uses API provided by libhdfs to manipulate Hadoop DFS.
> I could run the application with 1.0.4 and 1.1.1; setting classpath equal to 
> $(hadoop classpath).
> For Hadoop 2.0.3; setting CLASSPATH=$(hadoop classpath) does not load necessary classes required forlibhdfs; as opposed to 1.x versions; giving the following error:
> loadFileSystems error:
> (unable to get stack trace for java.lang.NoClassDefFoundError exception: ExceptionUtils::getStackTrace error.)
> hdfsBuilderConnect(forceNewInstance=0, nn=default, port=0, kerbTicketCachePath=(NULL), userName=(NULL)) error:
> (unable to get stack trace for java.lang.NoClassDefFoundError exception: ExceptionUtils::getStackTrace error.)
> I tried loading the jar files with their full path specified (as opposed to wildcard characters used in the classpath); and the application runs, but gives the following warning:
> SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
> SLF4J: Defaulting to no-operation (NOP) logger implementation
> SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
