# Verifying The Installation

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 trainMatch --conf examples/febrl/config.json`

The above will build Zingg models and use that to find duplicates in the **examples/febrl/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!
