+Chukwa is moving towards a model of using HBase to store metrics data to allow real-time
+charting. This section describes how to configure HBase and HICC to work together.
+Presently, we only support HBase 0.20.6. If you have HBase 0.89 jars anywhere, they 
+will cause linkage errors.  Check for and remove them.

+for coping with this case. </p>
 This mechanism can be enabled by setting option <code>httpConnector.asyncAcks</code>.
+This option applies to both agents and collectors. On the collector side, it tells
+the collector to return asynchronous acknowledgements. On the agent side, it tells
+agents to look for and process them correctly. Agents with the option set to false
+should work OK with collectors where it's set to true. The reverse is not
+generally true: agents will expect a collector to be able to answer questions
+about the state of the filesystem.
