-------------------------------------
Summary: Calcite Planner: 1.40 breaks coercion of smaller numeric
datatypes
Key: IMPALA-14429
URL: https://issues.apache.org/jira/browse/IMPALA-14429
Project: IMPALA
Issue Type: Sub-task
Reporter: Steve Carlin
In Calcite v1.37, we use coercenodes to change smaller datatypes to match
Impala types. For instance, the numeric '1' needs to be a tinyint in Impala,
whereas Calcite makes it an int (CALCITE-7120 is filed for this problem).
On upgrade from Calcite 1.37 to Calcite 1.40, the mechanism in coercenodes
fails because of work Calcite did in the AST portion of their code. So we need
to come up with another way to do this.
