* When the user uses a Connector to create a BatchWriter, they specify how much memory and how many threads it should use. As the user adds mutations to the
* batch writer, it buffers them. Once the buffered mutations have used half of the user specified buffer, the mutations are dumped into the background to be
* written by a thread pool. If the user specified memory completely fills up, then writes are held. When a user calls flush, it does not return until all
* buffered mutations are written.
+ * <p>
+ * In the event that an MutationsRejectedException exception is thrown by one of the methods on a BatchWriter instance, the user should close the current
+ * instance and create a new instance. This is a known limitation which will be addressed by ACCUMULO-2990 in the future.
