      Description

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

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

      BindAzureBlobMetadataToRequest 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 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.
