hdfs commands via hadoop deprecated? #1

If it is true that the use of the generic hadoop command is being deprecated (edit the hadoop command for comments) in favour of the specialised hdfs commands etc., maybe the examples should reflect that? E.g., in the README.md

hadoop fs -mkdir -p hip1/input

should become

hdfs dfs -mkdir -p hip1/input
