             Summary: Fast Decimal
                 Key: HIVE-15335
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: Matt McCline
            Assignee: Matt McCline
            Priority: Critical

Replace HiveDecimal implementation that currently represents the decimal 
internally as a BigDecimal with a faster version that does not allocate extra 

Replace HiveDecimalWritable implementation with a faster version that has new 
mutable* calls (e.g. mutableAdd, mutableEnforcePrecisionScale, etc) and stores 
the result as a fast decimal instead of a slow byte array containing a 
serialized BigInteger.

Provide faster ways to serialize/deserialize decimals.
