All Implemented Interfaces:

Serializable

@Public
public class RpcThrottlingException
extends HBaseIOException

Describe the throttling result. TODO: At some point this will be handled on the client side to prevent operation to go on the server if the waitInterval is greater than the one got as result of this exception.

fillInStackTrace

public Throwable fillInStackTrace()

There is little value in an RpcThrottlingException having a stack trace, since its cause is well understood without one. When a RegionServer is under heavy load and needs to serve many RpcThrottlingExceptions, skipping fillInStackTrace() will save CPU time and allocations, both here and later when the exception must be serialized over the wire.

Overrides:

fillInStackTrace in class Throwable
