[jira] [Created] (SPARK-9147) UnsafeRow should canonicalize NaN
values
Reynold Xin created SPARK-9147:
----------------------------------
Summary: UnsafeRow should canonicalize NaN values
Key: SPARK-9147
URL: https://issues.apache.org/jira/browse/SPARK-9147
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Reynold Xin
NaN has many different representations in raw bytes.
When we set a double/float value, we should check whether it is NaN, and a binary representation that is canonicalized, so we can do comparison on bytes directly.
