> hashCode does not work for byte[]
> ---------------------------------
>
> Key: STORM-139
> URL: https://issues.apache.org/jira/browse/STORM-139
> Project: Apache Storm
> Issue Type: Bug
> Reporter: James Xu

> https://github.com/nathanmarz/storm/issues/245
> Storm should use a different hashCode method when getting the hash for a
> byte[] array, since the default one uses the object identity. Should check
> the behavior on other arrays as well
> ----------
> xiaokang: I tested byte[] and other arrays. The hashCode of array is the
> array object identity.
> I alse tested that java.util.Arrays.hashCode(xx[]) is based of the array
> element's hash code. It maybe ok change the list-hash-code function of
> tuple.clj to fix the problem.
