> A couple of things: tabletsKeyValues is passed in but not returned -- the original map has to be updated, can't assign a new map to the variable otherwise the caller won't see it.
> Additionally, the caller always passes in a new map (never null). We should just assert that to be non-null. Checking for a non-null map is nonsensical for the previous reason as well.
> {code}
>     // only populate map after success
>     if (tabletsKeyValues == null) {
>       tabletsKeyValues = tkv;
>     } else {
>       tabletsKeyValues.clear();
>       tabletsKeyValues.putAll(tkv);
>     }
> {code}
