[GitHub] spark pull request: [SPARK-10380][SQL] Fix confusing documentation...

GitHub user rxin opened a pull request:

    https://github.com/apache/spark/pull/11698

    [SPARK-10380][SQL] Fix confusing documentation examples for astype/drop_duplicates.

    ## What changes were proposed in this pull request?
    We have seen users getting confused by the documentation for astype and drop_duplicates, because the examples in them do not use these functions (but do uses their aliases). This patch simply removes all examples for these functions, and say that they are aliases.
    
    ## How was this patch tested?
    Existing PySpark unit tests.

You can merge this pull request into a Git repository by running:

    This is public API, we should not break it randomly (even the doc).

    So my worry is that if we change cast in the future, the two would diverge.

    Do we want to have versions for these API?
    
    I think it's more clear to do this way:

         """ Convert the column into type ``dataType``.
