------------------------------------

             Summary: For Hadoop 2.0.3; setting CLASSPATH=$(hadoop classpath) 
does not work, as opposed to 1.x versions
                 Key: HDFS-4552
                 URL: https://issues.apache.org/jira/browse/HDFS-4552
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: libhdfs
    Affects Versions: 2.0.3-alpha
         Environment: Ubuntu 12.04 32 bit, java version "1.7.0_03"
c++ application
            Reporter: Shubhangi Garg


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.

library for your platform... using builtin-java classes where applicable
