------------------------------------

             Summary: Inconsistent mark-down for `Note:` across 
Scala/Java/R/Python in API documentations
                 Key: SPARK-18437
                 URL: https://issues.apache.org/jira/browse/SPARK-18437
             Project: Spark
          Issue Type: Improvement
          Components: Documentation
    Affects Versions: 2.0.1
            Reporter: Hyukjin Kwon


It seems in Scala/Java,

- {{Note:}}

- {{NOTE:}}

- {{Note that}}

- {{'''Note:'''}}}

are used in a mixed way. The last one seems correct as it marks down correctly. 
This will, for example, mark down it pretty[1].

Also, it seems some {{'''Note:'''}}s are wrongly placed[2] which looks like the 
{{Note:}} for the last argument (I believe it meant to be for the API).

For Python, 

- {{Note:}}

- {{NOTE:}}

- {{Note that}}

- {{.. note:}}}

In this case, I also believe the last one marks down pretty[3] rather than the 
others[4][5][6].

For R, it seems there are also,


- {{Note:}}

- {{NOTE:}}

- {{Note that}}

- {{@note}}}

In case of R, it seems pretty consistent. {{@note}} only contains the 
information about when the function came out such as {{locate since 1.5.0}} 
without other information[7]. So, I am not too sure for this.

It would be nicer if they are consistent, at least for Scala/Python/Java.
