-------------------------------------
Summary: Hash table lookup should be read-only
Key: IMPALA-9197
URL: https://issues.apache.org/jira/browse/IMPALA-9197
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Tim Armstrong
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.
