create a pipeline using data factory with copy activity from azure blob storage to data lake store

Question

I am trying to create a pipeline using data factory with copy activity from azure blob storage to data lake store.

But while running the pipeline it is showing status failed and getting below error:-

Copy activity encountered a user error at Source side: ErrorCode=UserErrorSourceBlobNotExist,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=The required Blob is missing. ContainerName: https://*********, ContainerExist: True, BlobPrefix: , BlobCount: 0.,Source=Microsoft.DataTransfer.ClientLibrary,'.

Answer 1

I follow the azure official tutorials to use data factory with copy activity from the azure blob storage to azure lake store. It works correctly on my side. We could create a pipeline by using the Azure portal , Visual Studio or powershell . We could follow the tutorials step by step to do that. The tutorials also supplied the following code.

• A linked service of type AzureStorage.

{
  "name": "StorageLinkedService",
  "properties": {
    "type": "AzureStorage",
    "typeProperties": {
      "connectionString": "DefaultEndpointsProtocol=https;AccountName=<accountname>;AccountKey=<accountkey>"
    }
  }
}

• A linked service of type AzureDataLakeStore.

{
    "name": "AzureDataLakeStoreLinkedService",
    "properties": {
        "type": "AzureDataLakeStore",
        "typeProperties": {
            "dataLakeStoreUri": "https://<accountname>.azuredatalakestore.net/webhdfs/v1",
            "servicePrincipalId": "<service principal id>",
            "servicePrincipalKey": "<service principal key>",
            "tenant": "<tenant info, e.g. microsoft.onmicrosoft.com>",
            "subscriptionId": "<subscription of ADLS>",
            "resourceGroupName": "<resource group of ADLS>"
        }
    }
}

• An input dataset of type AzureBlob.

{
  "name": "AzureBlobInput",
  "properties": {
    "type": "AzureBlob",
    "linkedServiceName": "StorageLinkedService",
    "typeProperties": {
      "folderPath": "mycontainer/myfolder/yearno={Year}/monthno={Month}/dayno={Day}",
      "partitionedBy": [
        {
          "name": "Year",
          "value": {
            "type": "DateTime",
            "date": "SliceStart",
            "format": "yyyy"
          }
        },
        {
          "name": "Month",
          "value": {
            "type": "DateTime",
            "date": "SliceStart",
            "format": "MM"
          }
        },
        {
          "name": "Day",
          "value": {
            "type": "DateTime",
            "date": "SliceStart",
            "format": "dd"
          }
        },
        {
          "name": "Hour",
          "value": {
            "type": "DateTime",
            "date": "SliceStart",
            "format": "HH"
          }
        }
      ]
    },
    "external": true,
    "availability": {
      "frequency": "Hour",
      "interval": 1
    },
    "policy": {
      "externalData": {
        "retryInterval": "00:01:00",
        "retryTimeout": "00:10:00",
        "maximumRetry": 3
      }
    }
  }
}

• An output dataset of type AzureDataLakeStore.

{
    "name": "AzureDataLakeStoreOutput",
      "properties": {
        "type": "AzureDataLakeStore",
        "linkedServiceName": "AzureDataLakeStoreLinkedService",
        "typeProperties": {
            "folderPath": "datalake/output/"
        },
        "availability": {
              "frequency": "Hour",
              "interval": 1
        }
      }
}

• A pipeline with a copy activity that uses BlobSource and AzureDataLakeStoreSink.

{  
    "name":"SamplePipeline",
    "properties":
    {  
        "start":"2014-06-01T18:00:00",
        "end":"2014-06-01T19:00:00",
        "description":"pipeline with copy activity",
        "activities":
        [  
              {
                "name": "AzureBlobtoDataLake",
                "description": "Copy Activity",
                "type": "Copy",
                "inputs": [
                  {
                    "name": "AzureBlobInput"
                  }
                ],
                "outputs": [
                  {
                    "name": "AzureDataLakeStoreOutput"
                  }
                ],
                "typeProperties": {
                    "source": {
                        "type": "BlobSource"
                      },
                      "sink": {
                        "type": "AzureDataLakeStoreSink"
                      }
                },
                   "scheduler": {
                      "frequency": "Hour",
                      "interval": 1
                },
                "policy": {
                      "concurrency": 1,
                      "executionPriorityOrder": "OldestFirst",
                      "retry": 0,
                      "timeout": "01:00:00"
                }
              }
        ]
    }
