> We should implement counter caching for DNS failure bucket metrics in
> ResolverThread to eliminate repeated HashMap lookups and standardize with
> NutchMetrics constants.
> ResolverThread.java creates dynamic counters for DNS failure buckets without
> caching, causing repeated context.getCounter() calls in the DNS resolution
> hot path. The counters also don't follow the standardized NutchMetrics
> constants pattern.
