----------------------------------------
Summary: hadoop-azure: page blob append support
Key: HADOOP-13195
URL: https://issues.apache.org/jira/browse/HADOOP-13195
Project: Hadoop Common
Issue Type: Improvement
Components: 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 {code}PageBlobOutputStream{code} can
be easily adapted to support appends. It already contains logic to re-upload
the last page if it's not full.
