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 i=
s 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(Of=
flineImageViewer.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: $HAD=
OOP_HOME is deprecated.) or there is something else?
I am having hadoop-1.2.1 version
