Resolves [SPARK-7743](https://issues.apache.org/jira/browse/SPARK-7743).

Trivial changes of versions, package names, as well as a small issue in `ParquetTableOperations.scala`

```diff
-    val readContext = getReadSupport(configuration).init(
+    val readContext = ParquetInputFormat.getReadSupportInstance(configuration).init(
```

Since ParquetInputFormat.getReadSupport was made package private in the latest release.
