Instead of "sbin" it is mentioned as "bin" in path to access script files.
To start/stop KMS use KMS's bin/kms.sh script. For example:
Run the new version with -upgrade option (bin/start-dfs.sh -upgrade).
3. start the cluster with rollback option. (bin/start-dfs.sh -rollback).
/bin/hadoop-daemon.sh --config $HADOOP_CONF_DIR --script "$bin"/hdfs start balancer [-policy <policy>]
Need to check for any other occurrences and fix the same
