> Hive 0.12 added support for new data types.  Pig 0.12 added some as well.  HCat should handle these as well.    Also note that CHAR was added recently.
> Also allow user to specify a parameter in Pig like so HCatStorer('','', '-onOutOfRangeValue Throw') to control what happens when Pig's value is out of range for target Hive column.  Valid values for the option are Throw and Null.  Throw - make the runtime raise an exception, Null, which is the default, means NULL is written to target column and a message to that effect is emitted to the log.  Only 1 message per column/data type is sent to the log.
> See attached HCat-Pig Type Mapping Hive 0.13.pdf for exact mappings.
