    Default Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName

    Hello,

    Can anyone please help me fix this exception. I have been stuck on this for quite sometime now.
    I am using an application called DistMap, a bioinformatics application which is designed to work on hadoop. But I am getting this error.

    Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/util/PlatformName

    Error could not create input directory /distmap_output_input folder on hdfs file system

    which java says

    /usr/java/jdk1.6.0_32/bin/java

    echo $CLASSPATH gives a blank line

    cat ~/.bash_profile says

    cat ~/.bash_profile
    # .bash_profile

    # Get the aliases and functions
    if [ -f ~/.bashrc ]; then
    . ~/.bashrc
    fi

    # User specific environment and startup programs

    PATH=$PATH:$HOME/bin

    export PATH

    Any suggestions?

    Thanks.
