You are right @caofangkun, not sure how that line got deleted, but it
shouldn't have been removed. I added back and I think the tests will pass now
> ConfigValidation.DoubleValidator doesn't really validate whether the type of

> ConfigValidation.DoubleValidator code only checks if the object is null
> whether if the object is a instance of Number which is a parent class of
> Double.
> DoubleValidator is only used once in Config.java and in that instance:
> public static final Object TOPOLOGY_STATS_SAMPLE_RATE_SCHEMA =
> ConfigValidation.DoubleValidator;
> can just be set to:
> public static final Object TOPOLOGY_STATS_SAMPLE_RATE_SCHEMA = NUMBER.class;
> Then we can just get rid of the misleading function
> ConfigValidation.DoubleValidator since it doesn't really check if a object is
> of double type thus the validator function doesn't really do anything and the
> name is misleading. In previous commit
> https://github.com/apache/storm/commit/214ee7454548b884c591991b1faea770d1478cec
> Number.Class was used anyway
