Constructor Detail

HadoopFileIO

public HadoopFileIO()

Constructor used for dynamic FileIO loading.

Hadoop configuration must be set through setConf(Configuration)

HadoopFileIO

public HadoopFileIO(org.apache.hadoop.conf.Configuration hadoopConf)

HadoopFileIO

public HadoopFileIO(SerializableSupplier<org.apache.hadoop.conf.Configuration> hadoopConf)

Method Detail

conf

public org.apache.hadoop.conf.Configuration conf()

newInputFile

public InputFile newInputFile(java.lang.String path)

Description copied from interface: FileIO

Get a InputFile instance to read bytes from the file at the given path.

Specified by:

newInputFile in interface FileIO

newOutputFile

public OutputFile newOutputFile(java.lang.String path)

Description copied from interface: FileIO

Get a OutputFile instance to write bytes to the file at the given path.

Specified by:

newOutputFile in interface FileIO

deleteFile

public void deleteFile(java.lang.String path)

Description copied from interface: FileIO

Delete the file at the given path.

Specified by:

deleteFile in interface FileIO

setConf

public void setConf(org.apache.hadoop.conf.Configuration conf)

Specified by:

setConf in interface org.apache.hadoop.conf.Configurable

getConf

public org.apache.hadoop.conf.Configuration getConf()

Specified by:

getConf in interface org.apache.hadoop.conf.Configurable

serializeConfWith

public void serializeConfWith(java.util.function.Function<org.apache.hadoop.conf.Configuration,SerializableSupplier<org.apache.hadoop.conf.Configuration>> confSerializer)

Description copied from interface: HadoopConfigurable

Take a function that serializes Hadoop configuration into a supplier. An implementation is supposed to pass in its current Hadoop configuration into this function, and the result can be safely serialized for future use.

Specified by:

serializeConfWith in interface HadoopConfigurable

Parameters:

confSerializer - A function that takes Hadoop configuration and returns a serializable supplier of it.
