Answer 1

Your file is not at hdfs:///user/hdfs/titles.csv , and this is what the error is saying.

You are only showing ls , not hdfs dfs -ls , so you should be using just cat titles.csv

If you want to read a file from HDFS, you need to hdfs dfs -put titles.csv /user/hdfs/ first. (And create the user directory using hdfs dfs -mkdir -p /user/hdfs if it doesn't already exist)
