+## A Note About Thrift JDBC server and CLI for Spark SQL
+
+Spark SQL supports Thrift JDBC server and CLI.
+See sql-programming-guide.md for more information about those features.
+You can use those features by setting `-Phive-thriftserver` when building Spark as follows.
+
+    $ sbt/sbt -Phive-thriftserver assembly
