Steve Carlin updated IMPALA-14165:
----------------------------------
Description:
On the first cut of creating the Calcite planner, the Calcite planner was
standalone and ran its own JniFrontend.
In the current version, the parsing, validating, and single node planning is
called from the Impala framework.
There is some code in the first cut regarding the "ImpalaTypeCoercionFactory"
class which handles deriving the correct data type for various expressions, for
instance (found in exprs.test):
10.1 in (tinyint_col, smallint_col, int_col, bigint_col, float_col, double_col)
This code was accidentally omitted in the current version and needs to be added.
