方法：

hive配置hiveserver2和metastore url

<!-- 指定hiveserver2连接的host -->
<property>
        <name>hive.server2.thrift.bind.host</name>
        <value>hadoop111</value>
</property>
    <!-- 指定hiveserver2连接的端口号 -->
<property>
        <name>hive.server2.thrift.port</name>
        <value>10000</value>
</property>


    <!-- 指定存储元数据要连接的地址 -->
<property>
        <name>hive.metastore.uris</name>
        <value>thrift://hadoop111:9083</value>
</property>

启动metastore

hive --service metastore

启动hiveserver2

hive --service hiveserver2

python代码

给个demo示例：

from pyspark.sql import SparkSession

# 创建 SparkSession
spark = SparkSession \
    .builder \
    .appName("HiveConnectionExample") \
    .config("spark.sql.warehouse.dir", "hdfs://192.168.10.111:8020/user/hive/warehouse") \
    .config("hive.metastore.uris", "thrift://192.168.10.111:9083") \
    .enableHiveSupport() \
    .getOrCreate()

# 读取 Hive 表
# df = spark.sql("SELECT * FROM a")
df = spark.sql("show tables")
df.show()

# 关闭 SparkSession
spark.stop()

运行成功
