How does Apache thrift fits with Apache hive?

Why do Apache Hive needs Apache Thrift? On the Thrift's site it says that it can compile in multiple languages, but I can't understand where does it fits and why do Hive need it. Thanks

https://cwiki.apache.org/confluence/display/Hive/HiveServer

HiveServer is an optional service that allows a remote client to submit requests to Hive, using a variety of programming languages, and retrieve results. HiveServer is built on Apache ThriftTM (http://thrift.apache.org/), therefore it is sometimes called the Thrift server although this can lead to confusion because a newer service named HiveServer2 is also built on Thrift.

For more details on how to connect to hive server(thrift server) see the link above.

Cited from safaribooksonline:

Chapter 16. Hive Thrift Service

Hive has an optional component known as HiveServer or HiveThrift that allows access to Hive over a single port. Thrift is a software framework for scalable cross-language services development. See http://thrift.apache.org/ for more details. Thrift allows clients using languages including Java, C++, Ruby, and many others, to programmatically access Hive remotely.

The CLI is the most common way to access Hive. However, the design of the CLI can make it difficult to use programmatically. The CLI is a fat client; it requires a local copy of all the Hive components and configuration as well as a copy of a Hadoop client and its configuration. Additionally, it works as an HDFS client, a MapReduce client, and a JDBC client (to access the metastore). Even with the proper client installation, having all of the correct network access can be difficult, especially across subnets or datacenters.

Couldn't have said it better. Emphasis mine.
