我正在尝试连接到由气流emr操作员启动的emr群集的雪花，但出现以下错误
py4j.protocol.py4jjavaerror:调用o147.load时出错：java.lang.classnotfoundexception:找不到数据源：net.snowflake.spark.snowflake。请在以下地址查找包裹http://spark.apache.org/third-party-projects.html
以下是我添加到emraddsteps操作符以运行脚本的步骤 load_updates.py 我在“args”里描述我的雪花包裹

STEPS = [
    {
        "Name" : "convo_facts",
        "ActionOnFailure" : "TERMINATE_CLUSTER",
        "HadoopJarStep" : {
            "Jar" : "command-runner.jar",
            "Args" : ["spark-submit", "s3://dev-data-lake/spark_files/cf/load_updates.py", \
                      "--packages net.snowflake:snowflake-jdbc:3.8.0,net.snowflake:spark-snowflake_2.11:2.4.14-spark_2.4", \
                      "INPUT=s3://dev-data-lake/table_exports/public/", \
                      "OUTPUT=s3://dev-data-lake/emr_output/cf/"]
        }
    }
]
JOB_FLOW_OVERRIDES = {
    'Name' : 'cftest',
    'LogUri' : 's3://dev-data-lake/emr_logs/cf/log.txt',
    'ReleaseLabel' : 'emr-5.32.0',
    'Instances' : {
        'InstanceGroups' : [
            {
                'Name' : 'Master nodes',
                'Market' : 'ON_DEMAND',
                'InstanceRole' : 'MASTER',
                'InstanceType' : 'r6g.4xlarge',
                'InstanceCount' : 1,
            },
            {
                'Name' : 'Slave nodes',
                'Market' : 'ON_DEMAND',
                'InstanceRole' : 'CORE',
                'InstanceType' : 'r6g.4xlarge',
                'InstanceCount' : 3,
            }
        ],
        'KeepJobFlowAliveWhenNoSteps' : True,
        'TerminationProtected' : False
    },
    'Applications' : [{
        'Name' : 'Spark'
    }],
    'JobFlowRole' : 'EMR_EC2_DefaultRole',
    'ServiceRole' : 'EMR_DefaultRole'
}

这就是我如何在我的load\u updates.py脚本中添加snowflake creds以提取到pysparkDataframe中。

# Set options below
sfOptions = {
  "sfURL" : "xxxx.us-east-1.snowflakecomputing.com",
  "sfUser" : "user",
  "sfPassword" : "xxxx",
  "sfDatabase" : "",
  "sfSchema" : "PUBLIC",
  "sfWarehouse" : ""
}
SNOWFLAKE_SOURCE_NAME = "net.snowflake.spark.snowflake"
query_sql = """select * from cf""";
messages_new = spark.read.format(SNOWFLAKE_SOURCE_NAME) \
  .options(**sfOptions) \
  .option("query", query_sql) \
  .load()

我不知道我是不是漏掉了什么或者哪里做错了。
