-----------------------------
Summary: ORC Vectorization DoubleColumnVector.isRepeating=false if
all entries are NaN
Key: HIVE-9711
URL: https://issues.apache.org/jira/browse/HIVE-9711
Project: Hive
Issue Type: Bug
Components: File Formats
Affects Versions: 1.2.0
Reporter: Gopal V
The isRepeating=true check uses Java equality, which results in NaN != NaN
comparison operations.
The noNulls case needs the current check folded into the previous loop, while
the hasNulls case needs a logical AND of the isNull[] field instead of ==
comparisons.
