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

Question

I know there have been many posts regarding this exception, but I am not able to fix this issue. Classpath has to be edited I think to resolve it. I am trying to run a program called DistMap in hadoop infrastructure. This is the error I am getting.

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

Update:

$HADOOP_HOME /usr/lib/hadoop

$HADOOP_CLASSPATH

/usr/lib/hadoop-0.20-mapreduce/hadoop-ant-2.0.0-mr1-cdh4.4.0.jar:/usr/lib/hadoop‌​-0.20-mapreduce/hadoop-ant.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-examples-2.0‌​.0-mr1-cdh4.4.0.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-examples.jar:/usr/lib/h‌​adoop-0.20-mapreduce/hadoop-core.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-core-2‌​.0.0-mr1-cdh4.4.0.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-test-2.0.0-mr1-cdh4.4‌​.0.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-test.jar:/usr/lib/hadoop-0.20-mapreduce/hadoop-tools-2.0.0-mr1-cdh4.4.0.jar:/usr/lib/hado‌​op-0.20-mapreduce/hadoop-tools.jar:/usr/lib/hadoop-0.20-mapreduce/lib/*jar:/usr/lib/hadoop/hadoop-common.jar:/usr/lib/hadoop/hadoop-common-2.0.0-cdh4.4.0.jar

The last 2 jar files have those classes PlatformName and FsShell. Still its not working.

Can anyone please help me fix this issue?

Thanks

Answer 1

hadoop-auth-2.2.0.jar should be there for hadoop2.2.0
Add hadoop auth jar for your version
