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
