Also, VERSION appears in the operating system's filesystem, not on HDFS.
Check out the dfs.name.dir property in ${HADOOP_HOME}/conf/hdfs-site.xml
for the location. The file is current/VERSION.

Stephen,
A NameNode can be considered 'formatted' if its up (it does not start
otherwise).
If you mean to check if the NameNode has been _freshly_ formatted,
then checking the count of "hadoop fs -ls /" to be non-zero may help,
cause by default the NameNode carries no files.
$ hadoop fs -ls / |
Hi,
VERSION does not appear to show up when running "hadoop dfs -lsr /"
it displays the files previously placed into hdfs . but nothing about
VERSION. I can see the VERSION file on the datanodes under the hdfs
managed data directoy
find /data | xargs ls -lrta | grep VERSION
-rw-rw
Hello Stephen,
You can use the VERSION file to verify that.
Regards,
Mohammad Tariq
