I found the same dir and files created in two places. /var/hadoop/hdfs/namenode/current/ and also under hadoop/hdfs/namenode/current/. All have root:root as their owner -rw-r--r-- 1 root root 201 Feb 13 10:12 VERSION

Change owner for /trvapps/hadoop/hdfs/namenode/current/VERSION to user starting namenode.

@Karthick T

Seems user starting namenode (usually hdfs) doesn't have ownership of version file "/trvapps/hadoop/hdfs/namenode/current/VERSION". Try again after changing ownership.
