      Description

      For IMPALA-9156, we need concurrent lookups to the hash table to be thread safe. We are pretty close to that, except a few stats are maintained in HashTable and would be modified concurrently from multiple threads.

      We should modify those places to update the stats in HashTableCtx instead.
