Can you rebase to see if the CI issue is fixed?

There's still a lint error here ``` Warning: src/main/java/org/apache/arrow/dataset/scanner/ArrowScannerReader.java:[43,3] (javadoc) JavadocMethod: Missing a Javadoc comment. ```

whoops, that should've been 17**7**32, thanks

CC @jduo, does this look reasonable as a basic landing page?

@davisusanibar @lwhite1 could one of you give this a skim? It would be good to have documentation for our shiny new driver.

We should probably add a unit test for this

No, although looking at it, the fix is a little weird - it means we're comparing data of two different types, or the data doesn't match its type? Regardless, it...

I think it's OK to have this, I wonder why the comparison doesn't start with a type comparison though (which should avoid this class of issues)
