How to start the Spark Thrift JDBC server

Spark SQL can serve JDBC and ODBC clients through the Spark Thrift Server, a HiveServer2-compatible endpoint that runs SQL queries on Spark. Starting the server fits environments where Beeline, BI tools, or application clients need SQL access without embedding Spark code in each client.

The start-thriftserver.sh wrapper launches a Spark application and accepts normal spark-submit options, so the same command shape can target local mode, Standalone, YARN, Kubernetes, or another configured master. The listener uses HiveServer2 properties for its bind host and TCP port.

Run the first check from the Spark installation directory and keep the listener bound to 127.0.0.1 until the local Beeline smoke test passes. Use a cluster master URI and a network-reachable bind host only when remote JDBC or ODBC clients are supposed to connect.

Steps to start the Spark Thrift JDBC server:

Change to the Spark installation directory.
```
$ cd /opt/spark
```
Use the directory that contains the Spark bin and sbin folders. The official Spark binary distribution includes sbin/start-thriftserver.sh.

Start the Thrift server in local mode.

$ ./sbin/start-thriftserver.sh \
  --master local[1] \
  --hiveconf hive.server2.thrift.bind.host=127.0.0.1 \
  --hiveconf hive.server2.thrift.port=10000
starting org.apache.spark.sql.hive.thriftserver.HiveThriftServer2, logging to /opt/spark/logs/spark-spark-org.apache.spark.sql.hive.thriftserver.HiveThriftServer2-1-spark-node.out

Replace local[1] with a cluster master such as spark://spark-master.example.com:7077 when the server should submit queries to a Spark cluster.

Connect with Beeline and run a SQL smoke test.

$ ./bin/beeline --silent=true \
  -u jdbc:hive2://127.0.0.1:10000/default \
  -n spark \
  -e "SELECT 1 AS id, upper('spark') AS engine;"
+-----+---------+
| id  | engine  |
+-----+---------+
| 1   | SPARK   |
+-----+---------+

The returned row proves that the JDBC endpoint is listening and that Spark SQL can execute work through the Thrift Server.

Stop the Thrift server after a local proof run when it should not remain available.
```
$ ./sbin/stop-thriftserver.sh
stopping org.apache.spark.sql.hive.thriftserver.HiveThriftServer2
```
Leave the process running only on hosts where the bind address, firewall rules, authentication, and catalog configuration are ready for JDBC or ODBC clients.
