Yin Huai updated SPARK-12454:
-----------------------------
Summary: Add ExpressionDescription to expressions that are registered in
FunctionRegistry (was: Add ExpressionDescription to expressions are registered
in FunctionRegistry)
> Add ExpressionDescription to expressions that are registered in
> FunctionRegistry
> --------------------------------------------------------------------------------
>
> Key: SPARK-12454
> URL: https://issues.apache.org/jira/browse/SPARK-12454
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Yin Huai
>
> ExpressionDescription is a annotation that contains doc of a function and
> when users use {{describe function}}, users can see the doc defined in this
> annotation. You can take a look at {{Upper}} as an example.
> However, we still have lots of expression that do not have
> ExpressionDescription. It will be great to take a look at expressions
> registered in FunctionRegistry and add ExpressionDescription to those
> expression that do not have it..
> A list of expressions (and their categories) registered in function registry
> can be found at
> https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/FunctionRegistry.scala#L117-L296.
