Subject: NullpointerException in OffLineImageViewer

I want to access and study the hadoop cluster's metadata which is stored in fsimage file on
namenode machine. i came to know that offLineImageViewer is used to do so. But when i am trying
doing it i am getting an exception.

/usr/hadoop/hadoop-1.2.1# bin/hadoop oiv -i fsimage -o fsimage.txt
Warning: $HADOOP_HOME is deprecated.

Exception in thread "main" java.lang.NullPointerException
at org.apache.hadoop.hdfs.tools.offlineImageViewer.OfflineImageViewer.go(OfflineImageViewer.java:141)
at org.apache.hadoop.hdfs.tools.offlineImageViewer.OfflineImageViewer.main(OfflineImageViewer.java:261)

i am not able to solve this error. Is it due to that warning (Warning: $HADOOP_HOME is deprecated.)
or there is something else?
I am having hadoop-1.2.1 version
