Installing Flink
In this section, we will download and install Apache Flink.
Flink runs on Linux, OS X, and Windows. To be able to run Flink, the only requirement is having a working Java 7.x (or higher) installation. If you are using Windows, please take a look at the Flink on Windows guide at https://ci.apache.org/projects/flink/flink-docs-release-1.4/start/flink_on_windows.html, which describes how to run Flink on Windows for local setups.
You can check your version of Java by issuing the following command:
java -version
If you have Java 8, the output will look something like this:
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
