> With KUDU-1802 implemented, the meta-cache in Kudu C++ client might crash if using a scan token with information on tablet location in scenarios like below:
> # Scan tokens were generated for table with multiple ranges (e.g., with two ranges: [-100, 0), [0, 100)).
> # First range was dropped (e.g., range [-100, 0) is dropped).
> # A client was fed a set of tokens generated at step 1 to read from the table (now with one stale token corresponding to the dropped range).
> # The same client instance was used to write into the table.
> # The same client instance fed the original set of tokens once more to read from the table again.
> The client would crash at step 5 of the sequence above.
> The stack trace on crash might look like this (captured on macOS):
