In the "/usr/hdp/2.6.0.3-8//hadoop-hdfs/bin/hdfs.distro" file the line 38 & 39 are as following:

   HADOOP_LIBEXEC_DIR=${HADOOP_LIBEXEC_DIR:-$DEFAULT_LIBEXEC_DIR}
   . $HADOOP_LIBEXEC_DIR/hdfs-config.sh

Looks like you have some environment variable issue whcih is setting incorrect HADOOP environment variable to point to an incorrect directory.

Can you please check where the "/root/hadoop-2.7.3" is being set at your end? In an ideal HDP environment that path does not exist.
