Integral literals are assumed to be INT by default, unless the number exceeds the range of INT in which case it is interpreted as a BIGINT, or if one of the following postfixes is present on the number.
String literals can be expressed with either single quotes (') or double quotes ("). Hive uses C-style escaping within the strings.
Floating point types
Floating point literals are assumed to be DOUBLE. Scientific notation is not yet supported.
