Review request for hive, Jesús Camacho Rodríguez, Zoltan Haindrich, and Vineet
Garg.
Bugs: HIVE-22250
https://issues.apache.org/jira/browse/HIVE-22250
Repository: hive-git
Description (updated)
-------
Describe function does not provide description for rank functions
=================================================================
The `DESCRIBE FUNCTION` command gets the description of a function from the
`@Description` annotations `value` field. If an UDF is annotated with the
`@WindowFunctionDescription` hive prints
```
There is no documentation for function <function>
```
Even if the description is present in the `@WindowFunctionDescription`
annotation.
This patch moves the `@WindowFunctionDescription.Description` field to a
separate annotation and provide the `@Description` annotation if both
annotations are missing.
