All Implemented Interfaces:

Serializable, SanitizableException

public class QueryInterruptedException
extends QueryException

Exception representing a failed query. The name "QueryInterruptedException" is a misnomer; this is actually used on the client side for *all* kinds of failed queries.

Fields: - "errorCode" is a well-defined errorCode code taken from a specific list (see the static constants). "Unknown exception" represents all wrapped exceptions other than interrupt, cancellation, resource limit exceeded, unauthorized request, and unsupported operation. - "errorMessage" is the toString of the wrapped exception - "errorClass" is the class of the wrapped exception - "host" is the host that the errorCode occurred on

The QueryResource is expected to emit the JSON form of this object when errors happen, and the DirectDruidClient deserializes and wraps them.
