Class Summary

Class	Description
ClientSideIteratorScanner	A scanner that instantiates iterators on the client side instead of on the tablet server.
Connector	Connector connects to an Accumulo instance and allows the user to request readers and writers for the instance as well as various objects that permit administrative operations.
IsolatedScanner	A scanner that presents a row isolated view of an accumulo table.

IsolatedScanner.MemoryRowBufferFactory
IteratorSetting	Configure an iterator for minc, majc, and/or scan.
IteratorSetting.Column	A convenience class for passing column family and column qualifiers to iterator configuration methods.
RowIterator	Group Key/Value pairs into Iterators over rows.
ZooKeeperInstance	An implementation of instance that looks in zookeeper to find information needed to connect to an instance of accumulo.
