Interface Summary

Interface	Description
Cell	The unit of storage in HBase consisting of the following fields:
CellScannable	Implementer can return a CellScanner over its Cell content.
CellScanner	An interface for iterating through a sequence of cells.
KeyValue.SamePrefixComparator<T>	Avoids redundant comparisons for better performance.
SettableSequenceId	Using this Interface one can mark a Cell as Sequence stampable.
SettableTimestamp	Using this Interface one can mark a Cell as timestamp changeable.
Stoppable	Implementers are Stoppable.

Class Summary

Class	Description
AuthUtil	Utility methods for helping with security tasks.
BaseConfigurable	HBase version of Hadoop's Configured class that doesn't initialize the configuration via BaseConfigurable.setConf(Configuration) in the constructor, but only sets the configuration through the BaseConfigurable.setConf(Configuration) method
CellComparator	Compare two HBase cells.
CellComparator.RowComparator	Counter part for the KeyValue.RowOnlyComparator
CellUtil	Utility methods helpful slinging Cell instances.
ChoreService	ChoreService is a service that can be used to schedule instances of ScheduledChore to run periodically while sharing threads.
CompoundConfiguration	Do a shallow merge of multiple KV configuration pools.
HBaseConfiguration	Adds HBase configuration files to a Configuration
HBaseInterfaceAudience	This class defines constants for different classes of hbase limited private apis
HConstants	HConstants holds a bunch of HBase-related constants
KeyValue	An HBase Key/Value.
KeyValue.KeyOnlyKeyValue	A simple form of KeyValue that creates a keyvalue with only the key part of the byte[] Mainly used in places where we need to compare two cells.
KeyValue.KVComparator	Compare KeyValues.
KeyValue.MetaComparator	A KeyValue.KVComparator for hbase:meta catalog table KeyValues.
KeyValue.RawBytesComparator	This is a TEST only Comparator used in TestSeekTo and TestReseekTo.
KeyValue.RowOnlyComparator	Comparator that compares row component only of a KeyValue.
KeyValueTestUtil
KeyValueUtil	static convenience methods for dealing with KeyValues and collections of KeyValues
NamespaceDescriptor	Namespace POJO class.
NamespaceDescriptor.Builder
ScheduledChore	ScheduledChore is a task performed on a period in hbase.
TableName	Immutable POJO class for representing a table name.
Tag	Tags are part of cells and helps to add metadata about the KVs.
TagType

Enum Summary

Enum	Description
HConstants.Modify	modifyTable op for replacing the table descriptor
HConstants.OperationStatusCode	Status codes used for return values of bulk operations.
KeyValue.Type	Key type.

Exception Summary

Exception	Description
HBaseIOException	All hbase specific IOExceptions should be subclasses of HBaseIOException

Annotation Types Summary

Annotation Type	Description
MetaMutationAnnotation	The field or the parameter to which this annotation can be applied only when it holds mutations for hbase:meta table.
VersionAnnotation	A package attribute that captures the version of hbase that was compiled.
