Subject: [PATCH] [SQL][Docs] Update the output of printSchema and fix a typo
in SQL programming guide.
We have changed the output format of `printSchema`. This PR will update our SQL programming guide to show the updated format. Also, it fixes a typo (the value type of `StructType` in Java API).
Author: Yin Huai <huai@cse.ohio-state.edu>
Closes #2630 from yhuai/sqlDoc and squashes the following commits:
267d63e [Yin Huai] Update the output of printSchema and fix a typo.
(cherry picked from commit 82a6a083a485140858bcd93d73adec59bb5cca64)
