Zoltan Haindrich updated HIVE-20913:
------------------------------------
Description:
CALCITE-1413 have added a logic to narrow an expression's type from nullable to
non-nullable - this causes some issues for Hive side sanity checks.
can be reproduced with a calcite 1.18.0-SNAPSHOT ; and
{{-Dtest=TestCliDriver#*[semijoin5]}}
{code}
java.lang.AssertionError:
Cannot add expression of different type to set:
set type is RecordType(INTEGER int_col, INTEGER int_col_1, BIGINT float_col,
BIGINT int_col_2) NOT NULL
expression type is RecordType(INTEGER NOT NULL int_col, INTEGER int_col_1,
BIGINT float_col, BIGINT int_col_2) NOT NULL
