All Known Implementing Classes:

HMSHandler

@InterfaceAudience.Private
public interface IHMSHandler
extends ThriftHiveMetastore.Iface, org.apache.hadoop.conf.Configurable

An interface wrapper for HMSHandler. This interface contains methods that need to be called by internal classes but that are not part of the thrift interface.

Method Detail

init

void init()
   throws MetaException

Throws:

MetaException

getMS

RawStore getMS()
        throws MetaException

Get a reference to the underlying RawStore.

Returns:

the RawStore instance.

Throws:

MetaException - if the creation of a new RawStore object is necessary but fails.

getTxnHandler

TxnStore getTxnHandler()

Get a reference to the underlying TxnStore.

Returns:

the TxnStore instance.

getWh

Warehouse getWh()

Get a reference to Hive's warehouse object (the class that does all the physical operations).

Returns:

Warehouse instance.

get_database_core

Database get_database_core(String catName,
                           String name)
                    throws NoSuchObjectException,
                           MetaException

Equivalent to get_database, but does not write to audit logs, or fire pre-event listeners. Meant to be used for internal hive classes that don't use the thrift interface.

Parameters:

catName - catalog name

name - database name

Returns:

database object

Throws:

NoSuchObjectException - If the database does not exist.

MetaException - If another error occurs.

get_table_core

@Deprecated
Table get_table_core(String catName,
                                 String dbname,

                                 NoSuchObjectException

Deprecated.

Equivalent of get_table, but does not log audits and fire pre-event listener. Meant to be used for calls made by other hive classes, that are not using the thrift interface.

Parameters:

catName - catalog name

dbname - database name

name - table name

Returns:

Table object

Throws:

NoSuchObjectException - If the table does not exist.

MetaException - If another error occurs.
