[SPARK-10584][SQL][DOC] Documentation about the compatible Hive version is wrong.

[sarutak]

In Spark 1.5.0, Spark SQL is compatible with Hive 0.12.0 through 1.2.1 but the documentation is wrong.

@liancheng We should say Hive 1.2.1 at here, right?

[liancheng]

Yeah right.

• This patch adds the following public classes (experimental):
  • case class TaskCommitDenied(
  • abstract class LocalNode(conf: SQLConf) extends QueryPlan[LocalNode] with Logging

[yhuai]

How about we say that Hive SerDes and UDFs are based on Hive 1.2.1, and Spark SQL can be connected to different versions of Hive Metastore (from 0.12.0 to 1.2.1. Also see http://spark.apache.org/docs/latest/sql-programming-guide.html#interacting-with-different-versions-of-hive-metastore). @marmbrus What do you think?

[sarutak]

Yeah, it's more clear. Thanks for your suggestion.

[srowen]

Was this related to #8739 ?

[yhuai]

@srowen Yeah, it is related to that. This one has two more changes for the doc.
