Я попытался запустить следующий пример кода чтения данных kusto из spark ноутбука.(Пример кода по ссылке: https://github.com/Azure/azure-kusto-spark/blob/dev/samples/src/main/scala/pyKusto.py)
from pyspark.sql import SparkSession
pyKusto = SparkSession.builder.appName("kustoPySpark").getOrCreate()
kustoOptions = {"kustoCluster":"<cluster-name>", "kustoDatabase" : "<database-name>", "kustoTable" : "<table-name>", "kustoAADClientID":"<AAD-app id>" ,"kustoClientAADClientPassword":"<AAD-app key>", "kustoAADAuthorityID":"<AAD authentication authority>"}
# Read the data from the kusto table in 'lean' mode
kustoDf = pyKusto.read. \
format("com.microsoft.kusto.spark.datasource"). \
option("kustoCluster", kustoOptions["kustoCluster"]). \
option("kustoDatabase", kustoOptions["kustoDatabase"]). \
option("kustoQuery", kustoOptions["kustoTable"]). \
option("kustoAADClientID", kustoOptions["kustoAADClientID"]). \
option("kustoClientAADClientPassword", kustoOptions["kustoClientAADClientPassword"]). \
option("kustoAADAuthorityID", kustoOptions["kustoAADAuthorityID"]). \
option("readMode", "lean"). \
load()
Выдает следующие исключения, ClassNotFoundException: Не удалось найти источник данных: com.microsoft.kusto.spark.datasource.
Кто-нибудь знает, как это исправить?
An error occurred while calling o97.load.
