databricks-datasets/SPARK_README.md

Apache Spark

Spark is a fast and general cluster computing system for Big Data. It provides
high-level APIs in Scala, Java, Python, and R, and an optimized engine that
supports general computation graphs for data analysis. It also supports a
rich set of higher-level tools including Spark SQL for SQL and DataFrames,
MLlib for machine learning, GraphX for graph processing,
and Spark Streaming for stream processing.

http://spark.apache.org/

Online Documentation

You can find the latest Spark documentation, including a programming
guide, on the project web page
and project wiki.
This README file only contains basic setup instructions.

Building Spark

Spark is built using Apache Maven.
To build Spark and its example programs, run:

build/mvn -DskipTests clean package

(You do not need to do this if you downloaded a pre-built package.)
More detailed documentation is available from the project site, at
"Building Spark".

Interactive Scala Shell

The easiest way to start using Spark is through the Scala shell:

./bin/spark-shell

Try the following command, which should return 1000:

scala> sc.parallelize(1 to 1000).count()

Interactive Python Shell

Alternatively, if you prefer Python, you can use the Python shell:

./bin/pyspark

And run the following command, which should also return 1000:

sc.parallelize(range(1000)).count()

Example Programs

Spark also comes with several sample programs in the examples directory.
To run one of them, use ./bin/run-example <class> [params]. For example:

./bin/run-example SparkPi

will run the Pi example locally.

You can set the MASTER environment variable when running examples to submit
examples to a cluster. This can be a mesos:// or spark:// URL,
"yarn" to run on YARN, and "local" to run
locally with one thread, or "local[N]" to run locally with N threads. You
can also use an abbreviated class name if the class is in the examples
package. For instance:

MASTER=spark://host:7077 ./bin/run-example SparkPi

Many of the example programs print usage help if no params are given.

Running Tests

Testing first requires building Spark. Once Spark is built, tests
can be run using:

./dev/run-tests

Please see the guidance on how to
run tests for a module, or individual tests.

A Note About Hadoop Versions

Spark uses the Hadoop core library to talk to HDFS and other Hadoop-supported
storage systems. Because the protocols have changed in different versions of
Hadoop, you must build Spark against the same version that your cluster runs.

Please refer to the build documentation at
"Specifying the Hadoop Version"
for detailed guidance on building for a particular distribution of Hadoop, including
building for particular Hive and Hive Thriftserver distributions.

Configuration

Please refer to the Configuration Guide
in the online documentation for an overview on how to configure Spark.

Airline On-Time Statistics and Delay Causes

Background

The U.S. Department of Transportation's (DOT) Bureau of Transportation Statistics (BTS) tracks >the on-time performance of domestic flights operated by large air carriers. Summary information >on the number of on-time, delayed, canceled and diverted flights appears in DOT's monthly Air >Travel Consumer Report, published about 30 days after the month's end, as well as in summary >tables posted on this website. BTS began collecting details on the causes of flight delays in >June 2003. Summary statistics and raw data are made available to the public at the time the Air >Travel Consumer Report is released.

bikeSharing/README.md

Bike Sharing Dataset

Hadi Fanaee-T

Laboratory of Artificial Intelligence and Decision Support (LIAAD), University of Porto
INESC Porto, Campus da FEUP
Rua Dr. Roberto Frias, 378
4200 - 465 Porto, Portugal

Background

Bike sharing systems are new generation of traditional bike rentals where whole process from >membership, rental and return
back has become automatic. Through these systems, user is able to easily rent a bike from a >particular position and return
back at another position. Currently, there are about over 500 bike-sharing programs around the >world which is composed of
over 500 thousands bicycles. Today, there exists great interest in these systems due to their >important role in traffic,
environmental and health issues.

Apart from interesting real world applications of bike sharing systems, the characteristics of >data being generated by
these systems make them attractive for the research. Opposed to other transport services such >as bus or subway, the duration
of travel, departure and arrival position is explicitly recorded in these systems. This feature >turns bike sharing system into
a virtual sensor network that can be used for sensing mobility in the city. Hence, it is >expected that most of important
events in the city could be detected via monitoring these data.

Dataset

Bike-sharing rental process is highly correlated to the environmental and seasonal settings. >For instance, weather conditions,
precipitation, day of week, season, hour of the day, etc. can affect the rental behaviors. The >core data set is related to

the two-year historical log corresponding to years 2011 and 2012 from Capital Bikeshare system, >Washington D.C., USA which is
publicly available in http://capitalbikeshare.com/system-data. We aggregated the data on two >hourly and daily basis and then
extracted and added the corresponding weather and seasonal information. Weather information are >extracted from http://www.freemeteo.com.

Associated Tasks

• Regression:

  • Predication of bike rental count hourly or daily based on the environmental and >seasonal settings.

• Event and Anomaly Detection:

  • Count of rented bikes are also correlated to some events in the town which easily are >traceable via search engines. For instance, query like "2012-10-30 washington d.c." in Google returns related results >to Hurricane Sandy. Some of the important events are identified in [1]. Therefore the data can be used for validation of anomaly or event >detection algorithms as well.

Files

• hour.csv : bike sharing counts aggregated on hourly basis. Records: 17379 hours
• day.csv : bike sharing counts aggregated on daily basis. Records: 731 days

Introduction

Fire Calls-For-Service includes all fire units responses to calls. Each record includes the >call number, incident number, address, unit identifier, call type, and disposition. All >relevant time intervals are also included. Because this dataset is based on responses, and >since most calls involved multiple units, there are multiple records for each call number. >Addresses are associated with a block number, intersection or call box, not a specific address.

sms_spam_collection/README.md

SMS Spam Collection v. 1

The SMS Spam Collection v.1 is a public set of SMS labeled messages that have been collected >for mobile phone spam research. It has one collection composed by 5,574 English, real and >non-enconded messages, tagged according being legitimate (ham) or spam.

Composition

This corpus has been collected from free or free for research sources at the Internet:

• A collection of 425 SMS spam messages was manually extracted from the Grumbletext Web site. >This is a UK forum in which cell phone users make public claims about SMS spam messages, most >of them without reporting the very spam message received. The identification of the text of >spam messages in the claims is a very hard and time-consuming task, and it involved carefully >scanning hundreds of web pages. The Grumbletext Web site is: http://www.grumbletext.co.uk/.
• A subset of 3,375 SMS randomly chosen ham messages of the NUS SMS Corpus (NSC), which is a >dataset of about 10,000 legitimate messages collected for research at the Department of >Computer Science at the National University of Singapore. The messages largely originate from >Singaporeans and mostly from students attending the University. These messages were collected >from volunteers who were made aware that their contributions were going to be made publicly >available. The NUS SMS Corpus is avalaible at: http://www.comp.nus.edu.sg/~rpnlpir/downloads/>corpora/smsCorpus/.
• A list of 450 SMS ham messages collected from Caroline Tag's PhD Thesis available at http://>etheses.bham.ac.uk/253/1/Tagg09PhD.pdf. Finally, we have incorporated the SMS Spam Corpus v.0.1 Big. It has 1,002 SMS ham messages and >322 spam messages and it is public available at: http://www.esp.uem.es/jmgomez/smsspamcorpus/.

TPC-H Data

The data in this directory was generated to run the TPC-H benchmark.

The TPC Benchmark™H (TPC-H) is a decision support benchmark. It consists of a suite of business >oriented
ad-hoc queries and concurrent data modifications. The queries and the data populating the >database have
been chosen to have broad industry-wide relevance. This benchmark illustrates decision support >systems
that examine large volumes of data, execute queries with a high degree of complexity, and give >answers
to critical business questions.
