More complex pipelines can be built from this project and run in similar manner. + +### Example Pipelines + +The following examples are included: + +1. [`WordCount`](https://github.com/apache/samza-beam-examples/blob/master/src/main/java/org/apache/beam/examples/WordCount.java) reads a file as input (bounded data source), and computes word frequencies. + +1. [`KafkaWordCount`](https://github.com/apache/samza-beam-examples/blob/master/src/main/java/org/apache/beam/examples/KafkaWordCount.java) does the same word-count computation but reading from a Kafka stream (unbounded data source). It uses a fixed 10-sec window to aggregate the counts. + +### Run Examples + +Each example can be run locally, in Yarn cluster or in standalone cluster. Here we use WordCount as an example. + +#### Set Up + +1. Download and install [JDK version 8](https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html). Verify that the JAVA_HOME environment variable is set and points to your JDK installation. + +1. Download and install [Apache Maven](http://maven.apache.org/download.cgi) by following Maven’s [installation guide](http://maven.apache.org/install.html) for your specific operating system. + +1. A script named "grid" is included in this project which allows you to easily download and install Zookeeper, Kafka, and Yarn. Review comment: I think all the individual line-items in SetUp(Install JDK, install maven, install grid) are numbered with 1. May be it would better to provide them right ordering. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
