在VS Code中运行Hadoop词频统计PowerShell脚本遇权限及空值错误

我在Visual Studio Code中编写了用于运行Hadoop词频统计的PowerShell脚本（保存为.ps1文件），执行时出现连锁错误：调用Start-AzHDInsightJob返回**Forbidden（禁止访问）**状态码，导致变量$wordCountJob为空；后续执行Wait-AzHDInsightJob时，因JobId参数为空触发报错。

脚本内容 #

Write-Host "Getting the context of your profile on Microsoft Azure..." -ForegroundColor Green 
$context = Get-AzContext

if ($null -eq $context) { Connect-AzAccount }

$context

$subscription = "5054f72b-16ed-4894-8bf5-fe7ad8fa20e3" 
$resourceGroupName = "BUS5WB" 
$clusterName = "bus5wb-hydra-s1-2022"

Write-Host "Selecting the subscription the HDInsight cluster is on..." -ForegroundColor Green 
Select-AzSubscription $subscription

Write-Host "Logging into the HDInsight cluster..." -ForegroundColor Green 
$cred = Get-Credential -Message "Enter the HDInsight cluster HTTP user credential:" 

$wordCountJobDefinition = New-AzHDInsightMapReduceJobDefinition     -JarFile "/example/jars/hadoop-mapreduce-examples.jar" -ClassName "wordcount"     -Arguments "/example/data/20450461/2Star.txt", ` "/example/data/20450461/2Star"

#Submit the job to the cluster 
Write-Host "Start the MapReduce job..." -ForegroundColor Green 
$wordCountJob = Start-AzHDInsightJob     -ClusterName $clusterName -JobDefinition $wordCountJobDefinition     -HttpCredential $cred -ResourceGroupName $resourceGroupName

#Wait for the job to complete 
Write-Host "Wait for the job to complete..." -ForegroundColor Green 
Wait-AzHDInsightJob     -ClusterName $clusterName -JobId $wordCountJob.JobId ` -HttpCredential $cred

错误输出内容 #
