--------------------------------------
Summary: Cast the column type for column masking
Key: HIVE-13486
URL: https://issues.apache.org/jira/browse/HIVE-13486
Project: Hive
Issue Type: Sub-task
Reporter: Pengcheng Xiong
Assignee: Pengcheng Xiong
Quoted from [~jdere] "in the case that getCellValueTransformer() returns a
constant value (such as "NULL" to indicate the expression should be null), the
resulting data type for that column ends up becoming the constant value NULL,
which is different from the original column's type. Might want to add a type
check somewhere to make sure the transformed expression and original expression
match, or maybe wrap the transformed expression within a CAST to get the types
to match."
