+ <h1 class="title">Apache Accumulo MapReduce Example</h1>
+ <p>This example uses mapreduce and accumulo to compute word counts for a set of
+documents. This is accomplished using a map-only mapreduce job and a
+accumulo table with combiners.</p>
+<p>To run this example you will need a directory in HDFS containing text files.
+The accumulo readme will be used to show how to run this example.</p>

+ <h1 class="title">Apache Accumulo MaxMutation Constraints Example</h1>
+ <p>This an example of how to limit the size of mutations that will be accepted into
+a table. Under the default configuration, accumulo does not provide a limitation
+on the size of mutations that can be ingested. Poorly behaved writers might
+inadvertently create mutations so large, that they cause the tablet servers to
+run out of memory. A simple contraint can be added to a table to reject very
+large mutations.</p>

+ <h1 class="title">Apache Accumulo Shard Example</h1>
+ <p>Accumulo has an iterator called the intersecting iterator which supports querying a term index that is partitioned by
+document, or "sharded". This example shows how to use the intersecting iterator through these four programs:</p>
+<ul>
+<li>Index.java - Indexes a set of text files into an Accumulo table</li>
+<li>Query.java - Finds documents containing a given set of terms.</li>
+<li>Reverse.java - Reads the index table and writes a map of documents to terms into another table.</li>
+<li>ContinuousQuery.java Uses the table populated by Reverse.java to select N random terms per document. Then it continuously and randomly queries those terms.</li>
+</ul>
+<p>To run these example programs, create two tables like below.</p>
+<div class="codehilite"><pre><span class="n">username</span><span class="nv">@instance</span><span class="o">></span> <span class="n">createtable</span> <span class="n">shard</span>
+<span class="n">username</span><span class="nv">@instance</span> <span class="n">shard</span><span class="o">></span> <span class="n">createtable</span> <span class="n">doc2term</span>
+</pre></div>
+
+
+<p>After creating the tables, index some files. The following command indexes all of the java files in the Accumulo source code.</p>
+<div class="codehilite"><pre><span class="nv">$</span> <span class="nv">cd</span> <span class="sr">/local/</span><span class="n">username</span><span class="sr">/workspace/</span><span class="n">accumulo</span><span class="o">/</span>
