I don't think so. For my YARN RPC service, a method was returning a boolean and it failed at that point with a class cast exception.
This method is also returning a {{IntegerRecord}} instead of an {{int}}.

> I think the [[ExtendedManagementProtocol.getAvailableSlots()]] method is returning an invalid type.
> Our RPC service is casing the return type of the RPC invocation to [[IOReadableWritable]]:
> https://github.com/apache/incubator-flink/blob/master/stratosphere-runtime/src/main/java/eu/stratosphere/nephele/ipc/RPC.java#L419
> This will lead to a ClassCastException at runtime.
> The method getAvailableSlots() is not used for any RPC requests (only for local testing, without an actual RPC call).
