在使用Apache Spark的spark-submit k8s API时，如果遇到https报错，可能是由于证书验证失败导致的。以下是解决方法的示例代码：

1. 禁用证书验证：

from pyspark.sql import SparkSession
from pyspark.conf import SparkConf

# 创建SparkSession
spark = SparkSession.builder \
    .appName("spark-submit k8s API with https") \
    .config("spark.kubernetes.authenticate.caCertFile", "/path/to/ca-certificate") \
    .config("spark.kubernetes.authenticate.clientKeyFile", "/path/to/client-key") \
    .config("spark.kubernetes.authenticate.clientCertFile", "/path/to/client-certificate") \
    .config("spark.kubernetes.authenticate.driver.serviceAccountName", "spark") \
    .config("spark.kubernetes.authenticate.submission.caCertFile", "/path/to/ca-certificate") \
    .config("spark.kubernetes.authenticate.submission.clientKeyFile", "/path/to/client-key") \
    .config("spark.kubernetes.authenticate.submission.clientCertFile", "/path/to/client-certificate") \
    .config("spark.kubernetes.authenticate.submission.oauthToken", "your-oauth-token") \
    .config("spark.kubernetes.authenticate.submission.oauthTokenFile", "/path/to/oauth-token-file") \
    .config("spark.kubernetes.authenticate.submission.oauthTokenSecret", "your-oauth-token-secret") \
    .config("spark.kubernetes.authenticate.submission.oauthTokenSecretFile", "/path/to/oauth-token-secret-file") \
    .config("spark.kubernetes.authenticate.submission.ssl.enabled", "false") \  # 禁用SSL验证
    .getOrCreate()

# 使用SparkSession执行Spark作业
df = spark.read.csv("/path/to/input/file.csv")
df.show()

2. 添加自定义证书：

from pyspark.sql import SparkSession
from pyspark.conf import SparkConf

# 创建SparkSession
spark = SparkSession.builder \
    .appName("spark-submit k8s API with https") \
    .config("spark.kubernetes.authenticate.caCertFile", "/path/to/ca-certificate") \
    .config("spark.kubernetes.authenticate.clientKeyFile", "/path/to/client-key") \
    .config("spark.kubernetes.authenticate.clientCertFile", "/path/to/client-certificate") \
    .config("spark.kubernetes.authenticate.driver.serviceAccountName", "spark") \
    .config("spark.kubernetes.authenticate.submission.caCertFile", "/path/to/ca-certificate") \
    .config("spark.kubernetes.authenticate.submission.clientKeyFile", "/path/to/client-key") \
    .config("spark.kubernetes.authenticate.submission.clientCertFile", "/path/to/client-certificate") \
    .config("spark.kubernetes.authenticate.submission.oauthToken", "your-oauth-token") \
    .config("spark.kubernetes.authenticate.submission.oauthTokenFile", "/path/to/oauth-token-file") \
    .config("spark.kubernetes.authenticate.submission.oauthTokenSecret", "your-oauth-token-secret") \
    .config("spark.kubernetes.authenticate.submission.oauthTokenSecretFile", "/path/to/oauth-token-secret-file") \
    .config("spark.kubernetes.authenticate.submission.ssl.enabled", "true") \
    .config("spark.kubernetes.authenticate.submission.ssl.caCertFile", "/path/to/custom-ca-certificate") \  # 添加自定义CA证书
    .config("spark.kubernetes.authenticate.submission.ssl.keyFile", "/path/to/custom-key") \  # 添加自定义私钥
    .config("spark.kubernetes.authenticate.submission.ssl.certFile", "/path/to/custom-certificate") \  # 添加自定义证书
    .getOrCreate()

# 使用SparkSession执行Spark作业
df = spark.read.csv("/path/to/input/file.csv")
df.show()

请根据实际情况修改上述代码中的证书文件路径和其他配置参数。
