Export-AzureRmDataLakeStoreItem：ADLSException：获取路径的元数据时出错

Question

当我尝试从Azure数据湖导出到本地驱动器驱动器时，我将得到以下提示。我的PS命令是这样的：

Export-AzureRmDataLakeStoreItem -AccountName $dataLakeStoreName 
-Path /Audit/ValidationLogs/Data_validation/MirrorValidations/test.csv -Destination "C:\sampledata\vehicle1_09142014_Copy.csv" -Concurrency 4

Error:

Export-AzureRmDataLakeStoreItem : ADLSException: Error in getting metadata for path 
/Audit/ValidationLogs/Data_validation/MirrorValidations/Mirror_validation_Report_Mastertables_Difference_SEP_Invoice.csv.
Operation: GETFILESTATUS failed with HttpStatus:ServiceUnavailable Error: Unexpected error in JSON parsing.

    + CategoryInfo          : CloseError: (:) [Export-AzureRmDataLakeStoreItem], CloudException

如果任何人有上述错误，请告诉我什么是分辨率。谢谢您的帮助。
