find /data | xargs ls -lrta | grep VERSION -rw-rw-r-- 1 hdfs hdfs 154 Aug 9 16:28 /data/1/dfs/dn/current/VERSION -rw-rw-r-- 1 hdfs hdfs 154 Aug 9 16:28 /data/2/dfs/dn/current/VERSION -rw-rw-r-- 1 hdfs hdfs 154 Aug 9 16:28 /data/3/dfs/dn/current/VERSION -rw-rw-r-- 1 hdfs hdfs 154 Aug 9 16:28 VERSION -rw-rw-r-- 1 hdfs hdfs 154 Aug 9 16:28 VERSION -rw-rw-r-- 1 hdfs hdfs 154 Aug 9 16:28 VERSION But using hadoop dfs does not see it ? 2012/8/9 Mohammad Tariq <donta...@gmail.com> > Hello Stephen, > > You can use the VERSION file to verify that. > > Regards, > Mohammad Tariq > > > On Fri, Aug 10, 2012 at 4:34 AM, Stephen Boesch <java...@gmail.com> wrote: > > > > Hi, what's your take?
