Method Detail

readFrom

public DatasetKeyInputFormat.ConfigBuilder readFrom(URI uri)

Adds configuration for DatasetKeyInputFormat to read from the given dataset or view URI.

URI formats are defined by Dataset implementations, but must begin with "dataset:" or "view:". For more information, see Datasets.

Parameters:

uri - a dataset or view URI

Returns:

this for method chaining

readFrom

public DatasetKeyInputFormat.ConfigBuilder readFrom(View<?> view)

Adds configuration for DatasetKeyInputFormat to read from the given Dataset or View instance.

Parameters:

view - a dataset or view

Returns:

this for method chaining

readFrom

public DatasetKeyInputFormat.ConfigBuilder readFrom(String uri)

Adds configuration for DatasetKeyInputFormat to read from the given dataset or view URI string.

URI formats are defined by Dataset implementations, but must begin with "dataset:" or "view:". For more information, see Datasets.

Parameters:

uri - a dataset or view URI string

Returns:

this for method chaining

withType

public <E> DatasetKeyInputFormat.ConfigBuilder withType(Class<E> type)

Sets the entity Class that the input Dataset should produce.

This Class is used to configure the input Dataset. If this class cannot be found during job setup, the job will fail and throw a TypeNotFoundException.

Parameters:

type - the entity Class that will be produced

Returns:

this for method chaining
