This documents how you run the simplest java examples.
+This tutorial uses the following Java classes, which can be found in
org.apache.accumulo.examples.simple.client in the examples-simple module:
+
+ * Flush.java - flushes a table
+ * RowOperations.java - reads and writes rows
+ * ReadWriteExample.java - creates a table, writes to it, and reads from it
+
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:
