--------------------------------------------------------------
There's (at least) 2 ways to solve this.
The patch way would be to set blob metadata on the way out. (ex. invoke
BlobMetadataToBlobProperties and pass that to sync.setBlobMetadata before
returning from putBlob).
The better way would be to modify AzureBlobAsyncClient.putBlockList to accept
another parameter, of metadata
`@BinderParam(BindMapToHeadersWithPrefix.class) Map<String, String> metadata`
Then add a corresponding parameter to AzureBlobClient.putBlockList
Finally, modify AzureBlobBlockUploadStrategy to use that parameter on the way
out.
hope this helps.

Ex. add the line here.
```
if (options.isMultipart()) {
String result = multipartUploadStrategy.get().execute(container, blob);
if (result != null) {
BlobMetadataToBlobProperties
sync.setBlobMetadata(container, blob.getName(),
return multipartUploadStrategy.get().execute(container, blob);
}
```

> Key: JCLOUDS-391
> URL: https://issues.apache.org/jira/browse/JCLOUDS-391
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-blobstore
> Affects Versions: 1.6.2
> Environment: Windows 7, Azure and S3
> Reporter: Klaus Müller
> Priority: Critical
>
> Try to set user defined meta data for Azure blob storage. No error setting
> meta data, but when I try to read them, they were not stored for the given
> blob.
> my code (small part of it):
> ...
> BlobStore blobStore = Context.getBlobStore();
> BlobBuilder builder = blobStore.blobBuilder("blob001");
> PayloadBlobBuilder payload = builder.payload(data); // data is
> InputStream
> payload.contentLength(datalen);
> Blob blob = payload.build();
> Map<String, String> keyValueMap = new HashMap<String, String>();
> keyValueMap.put("testmeta","12345");
> blob.getMetadata().setUserMetadata(keyValueMap);
> blobStore.putBlob("container001", blob, multipart() );
> ...
> For S3 it works.
> Is this a known problem with Azure, or something wrong with my code?
