Installation

Running from Docker image from Docker hub

The easiest way to get started is pulling the Docker image with the last release of Zingg.
docker pull zingg/zingg:0.3.3
docker run -it zingg/zingg:0.3.3 bash
Detailed help instructions for working with the Zingg docker image can be found here.

Installation

Zingg runs on Spark and can be used on all major Spark distributions. Zingg can run on all major Linux flavours.
Zingg is prebuilt for common Spark versions so you can use those directly. The following document assumes that we are installing Zingg 0.3 on Spark 3.1.2, but you can follow the same process for other versions too

Prerequisites

A) Java JDK - version "1.8.0_131"
B) Apache Spark - version spark-3.1.2-bin-hadoop3.2
Prerequisites for running Zingg on single machine without setting up a Spark cluster
(Good for a few million records) A) Install the specified JDK version
B) Apache Spark - Download the specified version from spark.apache.org and unzip it at a folder under home
Please add the following entries to ~/.bash_aliases
export JAVA_HOME=path to jdk
export SPARK_HOME=path to location of Apache Spark
export SPARK_MASTER=local[*]
C) Correct entry of host under /etc/hosts
Run ifconfig to find the ip of the machine and make sure it is added to the /etc/hosts for localhost
Prerequisites for running Zingg on a Spark cluster
If you have a ready Spark cluster, you can run Zingg by configuring the following environment on your driver machine
export JAVA_HOME=path to jdk
export SPARK_HOME=path to Apache Spark
export SPARK_MASTER=spark://master-host:master-port

Installation Steps

Download the tar zingg-version.tar.gz to a folder of your choice and run the following
gzip -d zingg-0.3.3-SNAPSHOT-bin.tar.gz ; tar xvf zingg-0.3.3-SNAPSHOT-bin.tar
This will create a folder zingg-0.3.1-SNAPSHOT under the chosen folder.
Move the above folder to zingg.
mv zingg-0.3.3-SNAPSHOT-bin ~/zingg
export ZINGG_HOME=path to zingg
export PATH=$PATH:$JAVA_HOME/bin:$SPARK_HOME/bin:$SPARK_HOME/sbin:ZINGG_HOME/scripts
Run bash and print the aliases to ensure that they are set correctly.
bash
echo $SPARK_HOME
echo $JAVA_HOME
java --version
echo $ZINGG_HOME
Let us now run a sample program to ensure that our installation is correct
cd zingg
./scripts/zingg.sh --phase match --conf examples/febrl/config.json
The above will find duplicates in the examples/febl/test.csv file. You will see Zingg logs on the console and once the job finishes, you will see some files under /tmp/zinggOutput with matching records sharing the same cluster id.
Congratulations, Zingg has been installed!

Compiling from sources

If you need to compile the latest code or build for a different Spark version, you can clone this repo and
  • Install maven (We are on version 3.3.9)
  • Install JDK 1.8
  • Set JAVA_HOME to JDK base directory
  • Run the following
mvn clean compile package -Dspark=sparkVer
where sparkVer is one of 2.4, 3.0 or 3.1
