3. (Microsoft SQL Server Only:) Configure Hive when Metastore DB is in a Named Instance

If your site uses Microsoft SQL Server for the Hive metadata store and the Hive database is not in the default instance (that is, in a named instance), you must configure the connection string after the installation completes:

On the Hive host, open the hive-site.xml file in a text editor.
Add the instance name to the property of the connection URL:
```
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:sqlserver://sql-host/instance-name:port/hive_db;create=true</value> 
<description>JDBC connect string for a JDBC metastore</description> 
</property>
```
where:
- sql-host is the SQL Server host name
- instance-name is the name of the instance that the Hive database is in
- hive_db is the name of the Hive database
Save the changes to hive-site.xml.
Finish configuring Hive as described later in this chapter, before restarting the Apache Hadoop Hive service.
