 ## Building With Hive and JDBC Support
 
 To enable Hive integration for Spark SQL along with its JDBC server and CLI,
 add the `-Phive` and `Phive-thriftserver` profiles to your existing build options.
-By default Spark will build with Hive 1.2.1 bindings.
+By default, Spark will build hadoop-2.7 with Hive 1.2.1, and can build hadoop-3.2 with Hive 2.3.5 optionally.
 
 Review comment:
   Something like "Spark will use Hive 1.2.1 with the `hadoop-2.7` profile, and Hive 2.3.5 with the `hadoop-3.2` profile.
