    As discussed, let's add the following variable:
    ```
    // TODO(zhitao): Remove this once `GROW_VOLUME` and `SHRINK_VOLUME` become
    // non-speculative.
    Resources resizedResources;
    ```



src/master/master.cpp

<https://reviews.apache.org/r/66050/#comment283687>

    As discussed, let's do:
    ```
    CHECK_EQ(1u, _conversions->size());
    const Resources& consumed = _conversions->at(0).consumed;
    const Resources& converted = _conversinos->at(0).converted;
    
    if (!_offeredResources.contains(consumed)) {
      drop(...);
      continue;
    }
    
    _offeredResources -= consumed;
    resizedResources += converted;
    ```
    here and below. We can drop r/66568.

    As discussed, let's do
    ```
    // TODO(zhitao): Remove `resizedResources` once `GROW_VOLUME` and
    // `SHRINK_VOLUME` become non-speculative.
    if (!_offeredResources.empty() || !resizedResources.empty()) {
      allocator->recoverResources(..., _offeredResources + resizedResources, 
...);
    }
    ```
