Download data

Get dataset of Kaggle Display Advertising Challenge from one of the following sources:

Original competition data (by Criteo Labs) [~20GB]
Subset of the original competition data (by Criteo Labs) [~30MB]
Tiny sample data (by the winners of the competition) [~20bytes]

It should be noted that you must accept and agree with CRITEO LABS DATA TERM OF USE before downloading the data.

Convert data into CSV format

Here, you can use a script prepared by one of the Hivemall PPMC members: takuti/criteo-ffm.

Clone the repository:

git clone git@github.com:takuti/criteo-ffm.git
cd criteo-ffm

A script data.sh downloads the original data and converts them into CSV format:

./data.sh  # downloads the original data and generates `train.csv` and `test.csv`
ln -s train.csv tr.csv
ln -s test.csv te.csv

Or, since the original data is very huge, starting from the tiny sample data bundled into the repository would be better:

ln -s train.tiny.csv tr.csv
ln -s test.tiny.csv te.csv

Create tables

Load the CSV files to Hive tables as:

hadoop fs -put tr.csv /criteo/train
hadoop fs -put te.csv /criteo/test
