Gopal V commented on HIVE-8760:
-------------------------------
bq. It's faster if you run w/o ATSHook, because the clone only happens there.
Cloning is fairly expensive.
+1 - this is a more contained fix for 0.14. This does not change any existing
behaviour or API contracts.
This will not break outside of ATSHook, which we can disable in case it shows
issues.
Copying always will be slow, but it runs the risk of changing the API contract
strictness too late for 0.14. Badly written hooks might fail, if they use the
common conf to pass variables between different hooks.
For a cleaner solution long-term (0.15+), I think we need a {{new
HiveConf(conf).asReadonly()}}, to enforce the API contract for such badly
behaving hooks.
