-----------------------------------
We had some user reports that {{"INVALIDATE METADATA `sometable`}} is
misleading too and may not help. Even after running it, the queries still
produce the warning. We need to try and reproduce this (or) consider rephrasing
it in a more meaningful way (or) remove it entirely.

> The Block locality stale warning message. ie.:
> WARNINGS: Read 348.13 MB of data across network that was expected to be
> local. Block locality metadata for table 'sometable' may be stale. Consider
> running "INVALIDATE METADATA `sometable`".
> Is misleading, it infers a data correctness issue where none exists. It
> should state that this issue carries only a performance impact and not a
> correctness one.
