> Consolidated behaviors for deleteRecursive and deleteRecursively in ZkClient
> ----------------------------------------------------------------------------
>
> Key: HELIX-679
> URL: https://issues.apache.org/jira/browse/HELIX-679
> Project: Apache Helix
> Issue Type: Bug
> Components: helix-core
> Reporter: Hao Zhang
> Priority: Major
>
> According to it's documentation `deleteRecursive()` should return true if
> operation is successful else false. But the semantics of the base function
> (`delete()`) it calls is different: it returns true if operation is
> successful, returns false if node does not exist, throws exception upon other
> errors, and therefore `deleteRecursive()` will also throw exception, and will
> return false if any sub-path is deleted already, which is confusing
> To consolidate semantics, we should either have the function only return
> true/false or only throw exception upon error.
>
> Also, to make change backward compatible, I'd propose the following change:
> # deleteRecursive() will only return true/false, and will not throw
> exception. If subpath does not exist, it should consider successful
> # create a new method called deleteRecursively() that will only throw
> exception upon error.
