Parameters:

job - System properties

tbl - table properties

Throws:

SerDeException

toInt

public static Integer toInt(String s)

deserialize

public Object deserialize(org.apache.hadoop.io.Writable field)
                   throws SerDeException

Description copied from class: AbstractDeserializer

Deserialize an object out of a Writable blob. In most cases, the return value of this function will be constant since the function will reuse the returned object. If the client wants to keep a copy of the object, the client needs to clone the returned value by calling ObjectInspectorUtils.getStandardObject().

Specified by:

deserialize in interface Deserializer

Specified by:

deserialize in class AbstractDeserializer

Parameters:

field - The Writable object containing a serialized object

Returns:

A Java object representing the contents in the blob.

Throws:

SerDeException

getObjectInspector

public ObjectInspector getObjectInspector()
                                   throws SerDeException

Description copied from class: AbstractDeserializer

Get the object inspector that can be used to navigate through the internal structure of the Object returned from deserialize(...).

Specified by:

getObjectInspector in interface Deserializer

Specified by:

getObjectInspector in class AbstractDeserializer

Throws:

SerDeException

main

public static void main(String[] args)

Parameters:

args -

getSerDeStats

public SerDeStats getSerDeStats()

Description copied from class: AbstractDeserializer

Returns statistics collected when serializing

Specified by:

getSerDeStats in interface Deserializer

Specified by:
