The "CRUD" acronym appears out of nowhere without explaining what it is, I assume it means "create, read, update and delete" but should be clarified.

There is something wrong with parenthesis () and [] in figure 2.3. After the transform part there is (russell.jurney@gmail.com, [******@hotmail.com)]. I believe that ought to be (russell.jurney@gmail.com, [******@hotmail.com]). Same mistake continues in the next parts of the figure.

The text mentions that "I have already created a venv environment in GitHub" ... where is this? I see that "venv" is on the ignore list.

The command to clone mongo-hadoop as written requires the user to log in to Github:

git clone git@github.com:rjurney/mongo-hadoop.git

Should be changed to

git clone https://github.com/rjurney/mongo-hadoop.git

There is an error in ch03/web/index.py on line 19. The result of the hash needs to be cast to string or re.search() will throw an error. Instead use:
results['values'] = [[s['from'], s['to'], s['total']] for s in sent_counts if re.search('apache', str(s['from'])) or re.search('apache', str(s['to']))]
of course substituting 'apache' for whatever it is you're looking for.
