The code seems to not stop really...

I have a 6 node Spark Cluster running PySpark3. Perhaps the issue boils down to how I have births_train saved.

I saved the file to my storage as a .csv and not a .csv.gz

base_dir = 'adl://dasciencestorage.azuredatalakestore.net/clusters/dascience/data/open_data/'
births = spark.read.csv(base_dir + 'births_train.csv',
header=True,
schema=schema)

The exact code giving me issues is anything that tries to display what is in births births.describe().show() or even your code that ends with .take(5)

Thoughts?

data = sc.parallelize(
[('Amber', 22), ('Alfred', 23), ('Skye',4), ('Albert', 12),
('Amber', 9)])

You don't show any importing, contextualizing or anything of the sort. Came here after buying the book and looking to actually save my confusion only to be more confused.

The code is looking for births_train.csv.gz file but I can't find the data file.

This code fragment in Chapter 4 example code does not work with Python 2.7:

fields = [
    *[
        typ.StructField(h[1:-1], typ.IntegerType(), True)
        for h in header.split(',')
    ]
]

It results in the SyntaxError: invalid syntax error.

Looks like this code is Python 3.x specific. It can be fixed by removing the inner *[ ... ] brackets.

Chapter03.ipynb.

%sql

select * from swimmersJSON

symtaxError: invalid syntax.

I am using google colab notebook for this.

I have tried %sql with BigQuery. it worked. Did anything change?

Thanks.

Hi,

Chapter2 notebook is going about chapter 3. Etc.
So chapter2 is missing.
Please update this.

Kind regards,
