Thrown when the coordinator reported itself as being overloaded.

This exception is processed by RetryPolicy.onErrorResponseVerdict(Request, CoordinatorException, int), which will decide if it is rethrown directly to the client or if the request should be retried.

Method Detail

copy

@NonNull
public DriverException copy()

Description copied from class: DriverException

Copy the exception.

This returns a new exception, equivalent to the original one, except that because a new object is created in the current thread, the top-most element in the stacktrace of the exception will refer to the current thread. The original exception may or may not be included as the copy's cause, depending on whether that is deemed useful (this is left to the discretion of each implementation).

This is intended for the synchronous wrapper methods of the driver, in order to produce a more user-friendly stack trace (that includes the line in the user code where the driver rethrew the error).
