> --------------------------------------

> Key: HADOOP-13195
> URL: https://issues.apache.org/jira/browse/HADOOP-13195
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/azure
> Reporter: Bogdan Raducanu

> The use case for this is storing transaction logs, which, unlike HBase logs, need to be appended, instead of created every time.
> Currently, hadoop-azure has append support but only for Block Blobs, which are not suited for transaction logging.
> After a quick look, I think the existing {{PageBlobOutputStream}} can be easily adapted to support appends. It already contains logic to re-upload the last page if it's not full.
