ssl - 无法使用 pySpark 从 Presto SQL (Trino) 获取数据

我有一个在 AWS Glue 上运行的 pyspark 作业。
当我通过本地机器运行代码时,它运行良好。
但是当我尝试从 AWS Glue 运行相同的代码时,我无法获取数据。
下面是我的代码和错误信息。
从输出中您会注意到我能够获取架构信息。一旦我尝试获取数据,就会发生错误。
更新 :
由于工作节点无法访问主节点中存在的 keystore ,因此问题正在发生。有人可以帮助如何将文件复制到子节点或如何使子节点可以访问文件吗?

import sys
from awsglue.transforms import *
from awsglue.utils import getResolvedOptions
from pyspark.context import SparkContext
from awsglue.context import GlueContext
from awsglue.job import Job

from pyspark.sql import SQLContext

## @params: [JOB_NAME]
args = getResolvedOptions(sys.argv, ['JOB_NAME'])

sc = SparkContext()
glueContext = GlueContext(sc)
spark = glueContext.spark_session
job = Job(glueContext)
sqlCont = SQLContext(spark)
job.init(args['JOB_NAME'], args)


query = "SELECT * FROM test.employee where id='1001'"

s3_client = boto3.client('s3')

s3_client.download_file('bucket1', 'rootca_ca.jks', '/tmp/rootca_ca.jks')


conparms_r = glueContext.extract_jdbc_conf("presto_test", catalog_id = None)

source_df = sqlCont.read.format("jdbc").option("driver","io.prestosql.jdbc.PrestoDriver").option("url", "jdbc:presto://test-db.net:18000/hive").option("query", query).option("user", conparms_r['user']).option("password", conparms_r['password']).option("SSL", True).option("SSLKeyStorePath","/tmp/rootca_ca.jks").option("SSLKeyStorePassword","test12").load()



print("************************************source_df SUCCESSFULLY CREATED !!!!!!!!!!!!!!!!!*****************************************")

source_df.printSchema()

source_df.show(5)
输出:

最佳答案

我能够通过将证书位置作为作业参数 --extra-files 来解决这个问题
并在代码中引用如下:

 source_df = sqlCont.read.format("jdbc").option("driver","io.prestosql.jdbc.PrestoDriver").option("url", "jdbc:presto://test-db.net:18000/hive").option("query", query).option("user", conparms_r['user']).option("password", conparms_r['password']).option("SSL", True).option("SSLKeyStorePath","./rootca_ca.jks").option("SSLKeyStorePassword","test12").load()
