Create an initialized record format for the given format specification. The name in the specification is first checked against standard names like "CSV" or "TSV". If it is a standard name, the corresponding format will be created, with specification settings applied on top of default settings. For example, "CSV" will map to the DelimitedStringsRecordFormat, with a comma as the delimiter, whereas "TSV" will map to the DelimitedStringsRecordFormat, with a tab as the delimiter. If the name is not a standard name, it is interpreted as a class name.

Type Parameters:

FROM - Type of underlying object the format reads

TO - Type of object the format reads the underlying object into

Parameters:

spec - the specification for the format to create and initialize

Returns:

Initialized RecordFormat based on the given name

Throws:

IllegalAccessException - if there was an illegal access when instantiating the record format

InstantiationException - if there was an exception instantiating the record format

ClassNotFoundException - if the record format class could not be found

co.cask.cdap.api.data.schema.UnsupportedTypeException - if the specification is not supported by the format
