+
+ <p>This documents how you run the simplest java examples.</p>
+<p>This tutorial uses the following Java classes, which can be found in org.apache.accumulo.examples.simple.client in the examples-simple module:</p>
+<ul>
+<li>Flush.java - flushes a table</li>
+<li>RowOperations.java - reads and writes rows</li>
+<li>ReadWriteExample.java - creates a table, writes to it, and reads from it</li>
+</ul>
+<p>Using the accumulo command, you can run the simple client examples by providing their
+class name, and enough arguments to find your accumulo instance. For example,
+the Flush class will flush a table:</p>

+
+ <p>This tutorial uses the following Java class, which can be found in org.apache.accumulo.examples.simple.combiner in the examples-simple module:</p>
+<ul>
+<li>StatsCombiner.java - a combiner that calculates max, min, sum, and count</li>
+</ul>
+<p>This is a simple combiner example. To build this example run maven and then
+copy the produced jar into the accumulo lib dir. This is already done in the
+tar distribution.</p>

+<p>In this example a table is created and the example stats combiner is applied to
+the column family stat and hstat. The stats combiner computes min,max,sum, and
+count. It can be configured to use a different base or radix. In the example
+above the column family stat is configured for base 10 and the column family
+hstat is configured for base 16.</p>
