Subject SQL specific documentation for recent Spark releases
Date Thu, 10 Aug 2017 20:46:26 GMT
While the DataFrame/DataSets are useful in many circumstances they are
cumbersome for many types of complex sql queries.

Is there an up to date *SQL* reference - i.e. not DataFrame DSL operations
- for version 2.2?

An example of what is not clear:  what constructs are supported within

    select count( predicate) from some_table

when using spark sql.

But in general the reference guide and programming guide for SQL seems to
be difficult to locate - seemingly in favor of the DataFrame/DataSets.
