Description

This version of Azure PowerShell HDInsight is deprecated. These cmdlets will be removed by January 1, 2017. Please use the newer version of Azure PowerShell HDInsight.

For information about how to use the new HDInsight to create a cluster, see Create Linux-based clusters in HDInsight using Azure PowerShell. For information about how to submit jobs by using Azure PowerShell and other approaches, see Submit Hadoop jobs in HDInsight. For reference information about Azure PowerShell HDInsight, see Azure HDInsight Cmdlets.

The Get-AzureHDInsightJobOutput cmdlet gets the log output for a job from the storage account associated with a cluster. You can get various types of job logs including standard output, standard error, task logs, and a summary of the task logs.

Examples

Example 1: Get job output

PS C:\>$SubId = (Get-AzureSubscription -Current).SubscriptionId
PS C:\> $ClusterName = "MyCluster"
PS C:\> $WordCountJob = New-AzureHDInsightMapReduceJobDefinition -JarFile "/Example/Apps/Hadoop-examples.jar" -ClassName "Wordcount" -Defines @{ "mapred.map.tasks" = "3" } -Arguments "/Example/Data/Gutenberg/Davinci.txt", "/Example/Output/WordCount" $WordCountJob
    | Start-AzureHDInsightJob -Subscription $SubId -Cluster $ClusterName
    | Wait-AzureHDInsightJob -Subscription $SubId -WaitTimeoutInSeconds 3600
    | Get-AzureHDInsightJobOutput -Cluster $ClusterName -StandardError

The first command gets the ID of the current subscription, and then stores it in the $SubId variable.

The second command stores the name MyCluster in the $Clustername variable.

The third command creates a MapReduce job definition, and then stores it in the $WordCountJob variable. The command passes the job in $WordCountJob to the Start-AzureHDInsightJob cmdlet to start the job. It also passes $WordCountJob to the Wait-AzureHDInsightJob cmdlet to wait for the job to finish, and then it uses Get-AzureHDInsightJobOutput to get the job output.
