Method Detail

write

public void write(DataOutput out)
           throws IOException

Description copied from interface: Writable

Serialize the fields of this object to out.

Specified by:

write in interface Writable

Parameters:

out - DataOuput to serialize this object into.

Throws:

IOException

readFields

public void readFields(DataInput in)
                throws IOException

Description copied from interface: Writable

Deserialize the fields of this object from in.

For efficiency, implementations should attempt to re-use storage in the existing object where possible.

Specified by:

readFields in interface Writable

Parameters:

in - DataInput to deseriablize this object from.

Throws:

IOException

getLength

public long getLength()

Description copied from class: InputSplit

Get the size of the split, so that the input splits can be sorted by size.

Specified by:

getLength in class InputSplit

Returns:

the number of bytes in the split

getId

public int getId()

getNumMaps

public int getNumMaps()

getReduceDurations

public long getReduceDurations(int i)

getLocations

public String[] getLocations()

Description copied from class: InputSplit

Get the list of nodes by name where the data for the split would be local. The locations do not need to be serialized.

Specified by:

getLocations in class InputSplit

Returns:

a new array of the node nodes.
