Method Detail

setSortBufferSize

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setSortBufferSize(int sortBufferSize)

Description copied from interface: org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder

Set the buffer size to use when sort the output

Specified by:

setSortBufferSize in interface org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder<OrderedPartitionedKVOutputConfig.SpecificBuilder>

Parameters:

sortBufferSize - the size of the buffer in MB

Returns:

instance of the current builder

setCombiner

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setCombiner(String combinerClassName)

Description copied from interface: org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder

Configure the combiner class

Specified by:

setCombiner in interface org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder<OrderedPartitionedKVOutputConfig.SpecificBuilder>

Parameters:

combinerClassName - the combiner class name

Returns:

instance of the current builder

setCombiner

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setCombiner(String combinerClassName,
                                                              Map<String,String> combinerConf)

Description copied from interface: org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder

Configure the combiner class and it's associated configuration (specified as key-value pairs). This method should only be used if the combiner requires some specific configuration. OrderedPartitionedKVOutputConfig.SpecificConfigBuilder.setCombiner(String) is the preferred method for setting a combiner.

Specified by:

setCombiner in interface org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder<OrderedPartitionedKVOutputConfig.SpecificBuilder>

Parameters:

combinerClassName - the combiner class name

combinerConf - the combiner configuration. This can be null, and otherwise is a Map of key-value pairs. The keys should be limited to the ones required by the combiner.

Returns:

instance of the current builder

setSorterNumThreads

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setSorterNumThreads(int numThreads)

Description copied from interface: org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder

Configure the number of threads to be used by the sorter

Specified by:

setSorterNumThreads in interface org.apache.tez.runtime.library.conf.OrderedPartitionedKVOutputConfig.SpecificConfigBuilder<OrderedPartitionedKVOutputConfig.SpecificBuilder>

Parameters:

numThreads - the number of threads

Returns:

instance of the current builder

setAdditionalConfiguration

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setAdditionalConfiguration(String key,
                                                                             String value)

Used to set additional configuration parameters which are not set via API methods. This is primarily meant for rarely used configuration options such as IFile read-ahead, configuring the number of parallel files to merge etc.

Parameters:

key - the key to set

value - the corresponding value

Returns:

this object for further chained method calls

setAdditionalConfiguration

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setAdditionalConfiguration(Map<String,String> confMap)

Used to set additional configuration parameters which are not set via API methods. This is primarily meant for rarely used configuration options such as IFile read-ahead, configuring the number of parallel files to merge etc.

Additionally keys set via this method are made available to the combiner.

Parameters:

confMap - map of configuration key-value pairs

Returns:

this object for further chained method calls

setFromConfiguration

public OrderedPartitionedKVOutputConfig.SpecificBuilder<E> setFromConfiguration(org.apache.hadoop.conf.Configuration conf)

Used to build out a configuration from an existing Hadoop Configuration. This is a private API is present only for compatibility and ease of use for existing systems which rely heavily on Configuration.

Returns:

this object for further chained method calls

done

public E done()
