     # Apache Accumulo Testing Suite
    +
    +The Apache Accumulo testing suite contains applications that test and verify the
    +correctness of Accumulo.
    +
    +## Installation
    +
    +In order to run the Apache Accumulo testing suite, you will need Java 8 and Maven installed
    +on your machine as well as an Accumulo instance to use for testing.
    +
    +1. First clone this repository.
    +
    +        git clone git@github.com:apache/accumulo-testing.git
    +        cd accumulo-testing
    +
    +2. All configuation files for the test suite are in `conf/`. Only the `accumulo-testing.props`
    +   configuration file needs to be created and edited. All other configuration files are
optional.
    +
    +        cd conf/
    +        cp accumulo-testing.props.example accumulo-testing.props
    +        vim accumulo-testing.props
    +
    +3. Tests are run using the `accumulo-testing` command which is located in the `bin/`
    +   directory. Run this command without any arguments to view its usage and see available
tests.
    +
    +        ./bin/accumulo-testing
    +
    +## Random walk test
    +
    +The random walk test generates client behavior on an Apache Accumulo instance by randomly
walking a
    +graph of client operations. The test is configured by the `accumulo-testing.props` file
and requires
    +a test module to be specified when run. See the [modules][modules] directory for available
modules.
    +The test can be run using single local process or multiple processes on a cluster using
YARN.
    +
    +The command below will start a local random walker using the [Image.xml][image] module.
    +
    +        ./bin/accumulo-testing rw-local Image.xml
    +
    +To run multiple random walkers on a cluster using YARN, set `test.container.instances`
in
    +`accumulo-testing.props` to the number of walkers that you want started and run the command
    +below.
    +
    +        ./bin/accumulo-testing rw-cluster Image.xml

    I'd suggest `rw-yarn` or `rw-twill` instead of `rw-cluster` for some future proofing.
