> 1) Currently,  KeyFieldBasedPartitioner only support utf8 encoded recored,  we should use text or byteswriteable data types.
> 2) when using KeyFieldBasedPartitioner, if the record doesn't contain the specified field, the endChar would equal with array.length, which throw ArrayOutOfIndex exception, losting that record!
