    +title: Apache Accumulo Examples
    +---
    +
    +## Setup instructions
    +
    +Before running any of the examples, the following steps must be performed.
    +
    +1. Install and run Accumulo via the instructions found in INSTALL.md.
    +   Remember the instance name. It will be referred to as "instance" throughout
    +   the examples. A comma-separated list of zookeeper servers will be referred
    +   to as "zookeepers".
    +
    +2. Create an Accumulo user (see the [user manual][1]), or use the root user.
    +   The "username" Accumulo user name with password "password" is used
    +   throughout the examples. This user needs the ability to create tables.
    +
    +In all commands, you will need to replace "instance", "zookeepers",
    +"username", and "password" with the values you set for your Accumulo instance.
    +
    +Commands intended to be run in bash are prefixed by '$'. These are always
    +assumed to be run the from the root of your Accumulo installation.
    +
    +Commands intended to be run in the Accumulo shell are prefixed by '>'.
    +

    +| [bulkIngest] | Ingesting bulk data using map/reduce jobs on Hadoop |
    +| [classpath] | Using per-table classpaths |
    +| [client] | Using table operations, reading and writing data in Java. |
