Interface Summary Interface Description BatchDeleter Implementations of BatchDeleter support efficient deletion of ranges in accumulo.BatchScanner In exchange for possibly returning scanned entries out of order, BatchScanner implementations may scan an Accumulo table more efficiently by Looking up multiple ranges in parallel.BatchWriter Send Mutations to a single Table in Accumulo.ConditionalWriter ConditionalWriter provides the ability to do efficient, atomic read-modify-write operations on rows.Instance This class represents the information a client needs to know to connect to an instance of accumulo.IsolatedScanner.RowBuffer IsolatedScanner.RowBufferFactory MultiTableBatchWriter This class enables efficient batch writing to multiple tables.Scanner Scans a table over a given range.ScannerBase This class hosts configuration methods that are shared between different types of scanners. -
Class Summary Class Description BatchWriterConfig This object holds configuration settings used to instantiate aBatchWriter
ClientConfiguration Contains a list of property keys recognized by the Accumulo client and convenience methods for setting them.ClientSideIteratorScanner A scanner that instantiates iterators on the client side instead of on the tablet server.ConditionalWriter.Result ConditionalWriterConfig 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.MemoryRowBuffer 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. -
Enum Summary Enum Description ClientConfiguration.ClientProperty ConditionalWriter.Status Durability The value for the durability of a BatchWriter or ConditionalWriter. -
Exception Summary Exception Description AccumuloException A generic Accumulo Exception for general accumulo failures.AccumuloSecurityException An Accumulo Exception for security violations, authentication failures, authorization failures, etc.MutationsRejectedException Communicate the failed mutations of a BatchWriter back to the client.NamespaceExistsException Thrown when the namespace specified already exists, and it was expected that it didn'tNamespaceNotEmptyException Thrown when the namespace specified contains tablesNamespaceNotFoundException Thrown when the namespace specified doesn't exist when it was expected toSampleNotPresentException Exception thrown when a table does not have sampling configured or when sampling is configured but it differs from what was requested.TableDeletedException This exception is thrown if a table is deleted after an operation starts.TableExistsException Thrown when the table specified already exists, and it was expected that it didn'tTableNotFoundException Thrown when the table specified doesn't exist when it was expected toTableOfflineException TimedOutException
