Carl Steinbach updated HIVE-2206:
---------------------------------
Status: Open (was: Patch Available)
Please explain what is preventing us from enabling this feature by default,
e.g. in which cases is it expected not to work, and what are the failure
scenarios?
Based on the current test coverage (not much) I can't tell if it's actually
possible to use this feature in its current state.
> add a new optimizer for query correlation discovery and optimization
