All Implemented Interfaces:

Serializable

public class FieldTypeNotSupportedException
extends DRException

Unchecked exception thrown to indicate a field in a record schema is of an invalid type for a given context.

Many operators which accept record types place constraints on the schema, typically constraining them to be flat (that is, not nested) or have fields of homogeneous type. This exception will generally be seen as the cause of a TypeNotSupportedException raised by such an operator.
