Summary: Insert into Hive tables doesn't work for decimal numbers
with no preceding digit before the decimal
Key: HIVE-24223

Any insert operation to a table in Hive with decimal integers without a digit
before the DOT ('.') fails with an exception as shown below:
------------------------------------------------------------------
hive> create table test_dec(id decimal(10,8));
hive> insert into test_dec values (-.5);

------------------------------------------------------------------
It seems to be coming from the Lexer where the types are defined and the
definition of 'Number' should be coming into play:
----------------------
Number : (Digit)+ ( DOT (Digit)* (Exponent)? | Exponent)? ;
----------------------

However, the below works:
-> insert into test_dec values ('-.5');
-> insert into test_dec values (-0.5);
