Package org.apache.hadoop.hive.metastore

Interface Summary

Interface	Description
AlterHandler	Interface for Alter Table and Alter Partition code
HiveMetaHook	HiveMetaHook defines notification methods which are invoked as part of transactions against the metastore, allowing external catalogs such as HBase to be kept in sync with Hive's metastore.
HiveMetaHookLoader	HiveMetaHookLoader is responsible for loading a HiveMetaHook for a given table.
IExtrapolatePartStatus
IHMSHandler
IMetaStoreClient	Wrapper around hive metastore thrift api
IMetaStoreClient.NotificationFilter	A filter provided by the client that determines if a given notification event should be returned.
MetaStoreFilterHook	Metadata filter hook for metastore client.
MetaStoreFS	Define a set of APIs that may vary in different environments
MetaStoreThread	A thread that runs in the metastore, separate from the threads in the thrift service.
PartitionExpressionProxy	The proxy interface that metastore uses to manipulate and apply serialized filter expressions coming from client.
RawStore

Class Summary

Class	Description
Deadline	This class is used to monitor long running methods in a thread.
DefaultMetaStoreFilterHookImpl	Default no-op implementation of the MetaStoreFilterHook that returns the result as is
HiveAlterHandler	Hive specific implementation of alter
HiveMetaStore	TODO:pc remove application logic to a separate interface.
HiveMetaStore.HiveMetastoreCli	HiveMetaStore specific CLI
HiveMetaStore.HMSHandler
HiveMetaStoreClient	Hive Metastore Client.
HiveMetaStoreFsImpl
HMSMetricsListener	Report metrics of metadata added, deleted by this Hive Metastore.
LinearExtrapolatePartStatus
LockComponentBuilder	A builder for LockComponents
LockRequestBuilder	Builder class to make constructing LockRequest easier.
MetaStoreEndFunctionContext	Base class which provides context to implementations of MetaStoreEndFunctionListener
MetaStoreEndFunctionListener	This abstract class needs to be extended to provide implementation of actions that need to be performed when a function ends.
MetaStoreEventListener	This abstract class needs to be extended to provide implementation of actions that needs to be performed when a particular event occurs on a metastore.
MetaStoreInit	MetaStoreInit defines functions to init/update MetaStore connection url.
MetaStoreInitContext	Base class which provides context to implementations of MetaStoreInitListener
MetaStoreInitListener	This abstract class needs to be extended to provide implementation of actions that needs to be performed when HMSHandler is initialized
MetaStorePreEventListener	This abstract class needs to be extended to provide implementation of actions that needs to be performed before a particular event occurs on a metastore.
MetaStoreSchemaInfo
MetaStoreUtils
ObjectStore	This class is the interface between the application logic and the database store that contains the objects.
ObjectStore.QueryWrapper	A class to pass the Query object to the caller to let the caller release resources by calling QueryWrapper.query.closeAll() after consuming all the query results.
PartitionDropOptions	Class to generalize the switches for dropPartitions().
ProtectMode
RawStoreProxy
RetryingHMSHandler
RetryingMetaStoreClient	RetryingMetaStoreClient.
SessionPropertiesListener	It handles the changed properties in the change event.
StatObjectConverter	This class contains conversion logic that creates Thrift stat objects from JDO stat objects and plain arrays from DirectSQL.
TServerSocketKeepAlive	TServerSocketKeepAlive - like TServerSocket, but will enable keepalive for accepted sockets.
TSetIpAddressProcessor<I extends ThriftHiveMetastore.Iface>	TSetIpAddressProcessor passes the IP address of the Thrift client to the HMSHandler.
TUGIBasedProcessor<I extends ThriftHiveMetastore.Iface>	TUGIBasedProcessor is used in unsecure mode for thrift metastore client server communication.
Warehouse	This class represents a warehouse where data of Hive tables is stored

IExtrapolatePartStatus.ColStatType	The sequence of colStatTypes.
TableType	Typesafe enum for types of tables described by the metastore.

Exception Summary

Exception	Description
