org.apache.hadoop.mapred.InvalidInputException: Input path does not exist

[anshuljoshi]

I am using the same notebook on Cloudera's quickstart VM and Anaconda installed. I have done no other changes.

On this step:

small_ratings_raw_data_header = small_ratings_raw_data.take(1)[0]

it gives an error:

I checked the previous step:

small_ratings_raw_data

This gives the result:

/home/cloudera/datasets/ml-latest-small/ratings.csv MapPartitionsRDD[7] at textFile at NativeMethodAccessorImpl.java:-2

Could you please help me with this?

What happened?
