Laljo John Pullokkaran commented on HIVE-9242:
----------------------------------------------
[~brocknoland] In this specific case exception is caught and thrown up as
runtime exception. I am guessing thats what you mean by CBO eating exceptions.
HiveException gets propagated through Calcite as a runtime exception; Without
changing a lot of plumbing in Calcite it would be difficult to explicitly throw
HiveException.
> Many places in CBO code eat exceptions

> I've noticed that there are a number of places in the CBO code which eat
> exceptions. This is not acceptable. Example:
