Numeric types with flipped back sign bit

[Svetozar Ivanov]

Is there a way to create numeric column in Apache Phoenix table or view 
with flipped back sign bit? I want to used TINYINT type for instance but 
in my HBase table is written value with flipped sign bit:

ROW COLUMN+CELL
 1                                              column=0:_0, 
timestamp=1435582427949, value=
 1                                              column=0:_boolean, 
timestamp=1435582427949, value=\x01
 1                                              column=0:_byte, 
timestamp=1435582427949, value=\x81

So obviously \x81 is 10000001 represented in binary format, I would 
expect 00000001 instead of it. Of course I want to use negative numbers 
too, that's why UNSIGNED_TINYINT type is not solution for me.
