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
KeyValue s. |
KeyValue.MetaKeyComparator | Compare key portion of a KeyValue for keys in .META.
table. |
KeyValue.RootComparator | A KeyValue.KVComparator for -ROOT- catalog table
KeyValue s. |
KeyValue.RootKeyComparator | Compare key portion of a KeyValue for keys in -ROOT- |
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 |
