> The eviction metrics are helpful for determining how much access-related
> churn there is in your block cache. The LruBlockCache properly ignores
> evictions by invalidation of HFile, but the BucketCache tracks them.
> We should make the BucketCache work similarly so that one can get an accurate
> view of the evictions occurring through too much random access or too large
> working set.
