> select trunc('millennium', cast('2001-02-16 20:38:40' as timestamp)) FAILED: SemanticException Line 0:-1 Argument type mismatch ''2001-02-16 20:38:40'': trunk() only takes STRING/CHAR/VARCHAR types as second argument, got TIMESTAMP
I saw this on a derivative of Hive 1.1.0 (cdh5.15.0), but the string still seems to be present on master:
