我正在尝试运行一个简单的spark程序来读取pycharm环境中的avro文件。我不断遇到这个我无法解决的错误。我感谢你的帮助。

from environment_variables import *
import avro.schema
from pyspark.sql import SparkSession

Schema = avro.schema.parse(open(SCHEMA_PATH, "rb").read())
print(Schema)
spark = SparkSession.builder.appName("indu").getOrCreate()
df = spark.read.format("avro").load(list(Schema))
print(df)

打印的模式如下所示

{"type": "record", "name": "DefaultEventRecord", "namespace": "io.divolte.record", "fields": [{"type": "boolean", "name": "detectedDuplicate"}, {"type": "boolean", "name": "detectedCorruption"}, {"type": "boolean", "name": "firstInSession"}, {"type": "long", "name": "clientTimestamp"}, {"type": "long", "name": "timestamp"}, {"type": "string", "name": "remoteHost"}, {"type": ["null", "string"], "name": "referer", "default": null}, {"type": ["null", "string"], "name": "location", "default": null}, {"type": ["null", "int"], "name": "devicePixelRatio", "default": null}, {"type": ["null", "int"], "name": "viewportPixelWidth", "default": null}, {"type": ["null", "int"], "name": "viewportPixelHeight", "default": null}, {"type": ["null", "int"], "name": "screenPixelWidth", "default": null}, {"type": ["null", "int"], "name": "screenPixelHeight", "default": null}, {"type": ["null", "string"], "name": "partyId", "default": null}, {"type": ["null", "string"], "name": "sessionId", "default": null}, {"type": ["null", "string"], "name": "pageViewId", "default": null}, {"type": ["null", "string"], "name": "eventId", "default": null}, {"type": "string", "name": "eventType", "default": "unknown"}, {"type": ["null", "string"], "name": "userAgentString", "default": null}, {"type": ["null", "string"], "name": "userAgentName", "default": null}, {"type": ["null", "string"], "name": "userAgentFamily", "default": null}, {"type": ["null", "string"], "name": "userAgentVendor", "default": null}, {"type": ["null", "string"], "name": "userAgentType", "default": null}, {"type": ["null", "string"], "name": "userAgentVersion", "default": null}, {"type": ["null", "string"], "name": "userAgentDeviceCategory", "default": null}, {"type": ["null", "string"], "name": "userAgentOsFamily", "default": null}, {"type": ["null", "string"], "name": "userAgentOsVersion", "default": null}, {"type": ["null", "string"], "name": "userAgentOsVendor", "default": null}, {"type": ["null", "int"], "name": "cityIdField", "default": null}, {"type": ["null", "string"], "name": "cityNameField", "default": null}, {"type": ["null", "string"], "name": "countryCodeField", "default": null}, {"type": ["null", "int"], "name": "countryIdField", "default": null}, {"type": ["null", "string"], "name": "countryNameField", "default": null}]}

得到的错误是，

21/03/02 16:06:50 WARN NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我感谢你的帮助。
