我正在尝试使用python从apache Spark中的postgres读取数据，但返回py4j.protocol.Py4JJavaError
这是我的代码：
import pyspark
from pyspark import SparkConf
from pyspark.sql import SparkSession
spark = SparkSession
.builder
.appName("PySpark Read")
.config("spark.jars", "C:sparkspark-2.4.5-bin-hadoop2.7jarspostgresql-42.2.12.jar")
.getOrCreate()
df = spark.read
.format("jdbc")
.option("driver", "org.postgresql.Driver")
.option("url", "jdbc:postgresql://127.0.0.1:5432/db_test")
.option("dbtable", "test")
.option("user", "postgres")
.option("password", "postgres")
.load()
df.printSchema()
这是错误日志：

顺便说一下，我在我的机器上本地运行我的 pyspark 脚本，我意识到有
致命：用户"postgres"的密码身份验证失败
但是，当我使用相同的凭据测试使用 Navicat 和 Dbeaver 进行连接时，它成功连接没有问题？我错过了什么吗？
根据@mazaneicha答案，它将我的 JDK 降级到 8u251(我以前的 JDK 是 14 或最新版本(后可以工作。
