Hadoop home path?

+1 vote

I am trying to run the below java code on a hadoop server.

javac -classpath ${HADOOP_HOME}/hadoop-${HADOOP_VERSION}-core.jar -d wordcount_classes WordCount.java

but I am not able to locate {HADOOP_HOME}. I tried with hadoop -classpath but it is giving output as below:

/etc/hadoop/conf:/usr/lib/hadoop/lib/*:/usr/lib/hadoop/.//*:/usr/lib/hadoop-hdfs/./:/usr/lib/hadoop-hdfs/lib/*:/usr/lib/hadoop-hdfs/.//*:/usr/lib/hadoop-yarn/.//*:/usr/lib/hadoop-0.20-mapreduce/./:/usr/lib/hadoop-0.20-mapreduce/lib/*:/usr/lib/hadoop-0.20-mapreduce/.//*

you can manually input the hadoop home path in the .bashrc file and make sure the same path is there in all these files (coresite, env.sh, hdfssite and yarnsite, mapred)
