Ashutosh Chauhan commented on HIVE-16888:
-----------------------------------------
Change of type string -> varchar(65535) cannot be assume to be safe. They are
different types. Calcite doesn't have a String type. So, Hive has special logic
on how to represent String type in Calcite. See, RexNodeConverter.java,
ExprNodeConverter and TypeConverter.
It should be investigated why this change occurred.
> Upgrade Calcite to 1.13 and Avatica to 1.10
