Method Detail

setReuseAvroValue

public void setReuseAvroValue(boolean reuseAvroValue)

Sets the flag whether to reuse the Avro value instance for all records. By default, the input format reuses the Avro value.

Parameters:

reuseAvroValue - True, if the input format should reuse the Avro value instance, false otherwise.

setUnsplittable

public void setUnsplittable(boolean unsplittable)

If set, the InputFormat will only read entire files.
