Description copied from interface: INativeSerializer

get length of data to be serialized. If the data length is already known (like IntWritable) and could immediately be returned from this method, it is good chance to implement customized NativeSerializer for efficiency

Specified by:

getLength in interface INativeSerializer<org.apache.hadoop.io.Writable>

Overrides:

getLength in class DefaultSerializer

Throws:

IOException
