SparkHashTableSinkOperator

public SparkHashTableSinkOperator(CompilationOpContext ctx)

Method Detail

initializeOp

protected void initializeOp(org.apache.hadoop.conf.Configuration hconf)
                     throws HiveException

Description copied from class: Operator

Operator specific initialization.

Overrides:

initializeOp in class Operator<SparkHashTableSinkDesc>

Throws:

HiveException

process

public void process(Object row,
                    int tag)
             throws HiveException

Description copied from class: Operator

Process the row.

Specified by:

process in class Operator<SparkHashTableSinkDesc>

Parameters:

row - The object representing the row.

tag - The tag of the row usually means which parent this row comes from. Rows with the same tag should have exactly the same rowInspector all the time.

Throws:

public void closeOp(boolean abort)
             throws HiveException

Description copied from class: Operator

Operator specific close routine. Operators which inherents this class should overwrite this funtion for their specific cleanup routine.

Overrides:

closeOp in class Operator<SparkHashTableSinkDesc>

Throws:

HiveException

flushToFile

protected void flushToFile(MapJoinPersistableTableContainer tableContainer,
                           byte tag)
                    throws Exception

Description copied from class: Operator

Return the type of the specific operator among the types in OperatorType.

Specified by:

getType in class Operator<SparkHashTableSinkDesc>

Returns:

OperatorType.*
