Interface Summary
Abortable Interface to support the aborting of a given server or client.
Server Defines the set of shared functions implemented by HBase servers (Masters and RegionServers).
Stoppable Implementers are Stoppable.
 

Class Summary
Chore Chore is a task performed on a period in hbase.
ClusterStatus Status information on the HBase cluster.
HBaseConfiguration Adds HBase configuration files to a Configuration
HColumnDescriptor An HColumnDescriptor contains information about a column family such as the number of versions, compression settings, etc.
HConstants HConstants holds a bunch of HBase-related constants
HMsg HMsg is used to send messages between master and regionservers.
HRegionInfo HRegion information.
HRegionLocation Contains the HRegionInfo for the region and the HServerAddress for the HRegionServer serving the region
HServerAddress HServerAddress is a "label" for a HBase server made of host and port number.
HServerInfo HServerInfo is meta info about an HRegionServer.
HServerInfo.LoadComparator Orders HServerInfos by load then name.
HServerLoad This class encapsulates metrics for determining the load on a HRegionServer
HServerLoad.RegionLoad Encapsulates per-region loading metrics.
HTableDescriptor HTableDescriptor contains the name of an HTable, and its column families.
KeyValue An HBase Key/Value.
KeyValue.KeyComparator Compare key portion of a KeyValue.
KeyValue.KVComparator Compare KeyValues.
KeyValue.MetaComparator A KeyValue.KVComparator for .META. catalog table KeyValues.
KeyValue.MetaKeyComparator Compare key portion of a KeyValue for keys in .META. table.
KeyValue.RootComparator A KeyValue.KVComparator for -ROOT- catalog table KeyValues.
KeyValue.RootKeyComparator Compare key portion of a KeyValue for keys in -ROOT- table.
KeyValue.RowComparator Comparator that compares row component only of a KeyValue.
KeyValue.SplitKeyValue Utility class that splits a KeyValue buffer into separate byte arrays.
LocalHBaseCluster This class creates a single process HBase cluster.
MasterAddressTracker Manages the location of the current active Master for this RegionServer.
RemoteExceptionHandler An immutable class which contains a static method for handling org.apache.hadoop.ipc.RemoteException exceptions.
 

Enum Summary
HColumnDescriptor.CompressionType Deprecated. Compression now means which compression library rather than 'what' to compress.
HConstants.Modify modifyTable op for replacing the table descriptor
HConstants.OperationStatusCode Status codes used for return values of bulk operations.
HMsg.Type  
KeyValue.Type Key type.
 

Exception Summary
ClockOutOfSyncException This exception is thrown by the master when a region server clock skew is too high.
DoNotRetryIOException Subclass if exception is not meant to be retried: e.g.
DroppedSnapshotException Thrown during flush if the possibility snapshot content was not properly persisted into store files.
InvalidFamilyOperationException Thrown if a request is table schema modification is requested but made for an invalid family name.
MasterNotRunningException Thrown if the master is not running
NotAllMetaRegionsOnlineException Thrown when an operation requires the root and all meta regions to be online
NotServingRegionException Thrown by a region server if it is sent a request for a region it is not serving.
PleaseHoldException This exception is thrown by the master when a region server was shut down and restarted so fast that the master still hasn't processed the server shutdown of the first instance.
RegionException Thrown when something happens related to region handling.
TableExistsException Thrown when a table exists but should not
TableNotDisabledException Thrown if a table should be offline but is not
TableNotFoundException Thrown when a table can not be located
UnknownRegionException Thrown when we are asked to operate on a region we know nothing about.
UnknownRowLockException Thrown if a region server is passed an unknown row lock id
UnknownScannerException Thrown if a region server is passed an unknown scanner id.
YouAreDeadException This exception is thrown by the master when a region server reports and is already being processed as dead.
ZooKeeperConnectionException Thrown if the client can't connect to zookeeper
