             Summary: Should not use the private field of BigInteger
                 Key: SPARK-10095
                 URL: https://issues.apache.org/jira/browse/SPARK-10095
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 1.5.0
            Reporter: Davies Liu
            Assignee: Davies Liu
            Priority: Minor


In UnsafeRow, we use the private field of BigInteger for better performance, 
but it actually didn't contribute much to end-to-end runtime, and make it not 
portable (may fail on other JVM implementations).

So we should use the public API instead.
