We are trying to download a file present in Data Lake Store. I have been following the below tutorial which uses .Net Azure SDk.

https://azure.microsoft.com/en-us/documentation/articles/data-lake-analytics-get-started-net-sdk/

As we have already the file present in Azure Data Lake Store , I just added the code to download the file

FileCreateOpenAndAppendResponse beginOpenResponse = _dataLakeStoreFileSystemClient.FileSystem.BeginOpen("/XXXX/XXXX/test.csv", DataLakeStoreAccountName, new FileOpenParameters());
            FileOpenResponse openResponse = _dataLakeStoreFileSystemClient.FileSystem.Open(beginOpenResponse.Location);

But it's failing with the below error

{"RemoteException":{"exception":"RuntimeException","message":"FsOpenStream failed with error 0x83090aa2 (). [83271af3c3a14973ad7814e7d9d201f6]","javaClassName":"java.lang.RuntimeException"}}

While debugging we inspected the beginOpenResponse.Location that been used in the second line code. It seems to the correct value as below

https://XXXXXXXX.azuredatalakestore.net/webhdfs/v1/XXXX/XXX/test.csv?op=OPEN&api-version=2015-10-01-preview&read=true

The error does not provide much information to track down the problem.

I agree that the store errors are currently non-printable comment. We are working on improving this.

According to my store developer, 0x83090aa2 is access check failed. Can you please check if you have access to the storage account and/or the path is correct?
