Method Detail

init

public void init(HiveConf hiveConf)

Description copied from class: AbstractService

Initialize the service. The transition must be from Service.STATE.NOTINITED to Service.STATE.INITED unless the operation failed and an exception was raised.

Specified by:

init in interface Service

Overrides:

init in class CompositeService

start

public void start()

Description copied from class: AbstractService

Start the service. The transition should be from Service.STATE.INITED to Service.STATE.STARTED unless the operation failed and an exception was raised.

stop

public void stop()

Description copied from class: AbstractService

Stop the service. This operation must be designed to complete regardless of the initial state of the service, including the state of all its internal fields.

Specified by:

stop in interface Service

Overrides:

stop in class CompositeService

openSession

public SessionHandle openSession(TProtocolVersion protocol,
                        String username,
                        String password,
                        String ipAddress,
                        Map<String,String> sessionConf)
                          throws HiveSQLException

Throws:

HiveSQLException

openSession

public SessionHandle openSession(TProtocolVersion protocol,
                        String username,
                        String password,
                        String ipAddress,
                        Map<String,String> sessionConf,
                        boolean withImpersonation,
                        String delegationToken)
                          throws HiveSQLException

Opens a new session and creates a session handle. The username passed to this method is the effective username. If withImpersonation is true (==doAs true) we wrap all the calls in HiveSession within a UGI.doAs, where UGI corresponds to the effective user.

Parameters:

protocol -

username -

password -

ipAddress -

sessionConf -

withImpersonation -

delegationToken -

Returns:

Throws:
