Subject [jira] [Created] (JCLOUDS-1487) Blob content length is mandatory while uploading to Azure
Date Tue, 15 Jan 2019 19:39:00 GMT
Alexander Chernavin created JCLOUDS-1487:
--------------------------------------------

             Summary: Blob content length is mandatory while uploading to Azure
                 Key: JCLOUDS-1487
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-1487
             Project: jclouds
          Issue Type: Bug
          Components: jclouds-blobstore
    Affects Versions: 2.1.1
            Reporter: Alexander Chernavin
         Attachments: length_exception.txt

Content length is mandatory while uploading to Azure using JClouds portable Blob Store API

 

Code example:

Blob blob = blobStore.blobBuilder(blobName)
 .payload(new InputStreamPayload(inputStream))
 .contentType(contentType)
 .build();

blobStore.putBlob(container, blob);

 

[BindAzureBlobMetadataToRequest|https://github.com/fusesource/jclouds/blame/master/providers/azureblob/src/main/java/org/jclouds/azureblob/binders/BindAzureBlobMetadataToRequest.java] class
checks that content length is specified and is greater than zero in lines 58-59. However,
according to the Azure SDK documentation, Azure [CloudBlockBlob|https://azure.github.io/azure-sdk-for-java/com/microsoft/azure/storage/blob/CloudBlockBlob.html#upload-java.io.InputStream-long-]
also accepts -1 if content length is unknown: 

{{length}} - A {{long}} which represents the length, in bytes, of the stream data, or -1
if unknown.

 

We have a use case when we need to stream a big chunk of data of unknown size directly into
a cloud storage. Portable JClouds API allows to upload files into OpenStack SWIFT without
specifying their size, but it fails on Azure.
