Package org.apache.hadoop.hive.metastore

Interface Summary

Interface	Description
FileFormatProxy	Same as PartitionExpressionProxy, but for file format specific methods for metadata cache.
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.
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.
MetadataStore
Metastore.SplitInfoOrBuilder
Metastore.SplitInfosOrBuilder
MetaStoreFilterHook	Metadata filter hook for metastore client.
MetaStoreFS	Define a set of APIs that may vary in different environments
MetaStorePasswdAuthenticationProvider
MetastoreTaskThread	Any task that will run as a separate thread in the metastore should implement this interface.
PartitionExpressionProxy	The proxy interface that metastore uses for variety of QL operations (metastore can't depend on QL because QL depends on metastore; creating metastore-client module would be a proper way to solve this problem).

Class Summary
