-------------------------------------
Summary: S3AInputStream#unbuffer should merge input stream stats
fs-wide stats
Key: HADOOP-16379
URL: https://issues.apache.org/jira/browse/HADOOP-16379
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Sahil Takiar
Assignee: Sahil Takiar
HADOOP-14747 added support for {{CanUnbuffer}} to S3A. One issue for
applications that rely on the {{CanUnbuffer}} functionality, is that the
current S3A code only merges input stream stats when the stream is closed.
Applications using {{CanUnbuffer}} might not close streams for a long time, so
any stats reported by input streams don't get reported in the filesystem-wide
metrics.
This JIRA proposes merging input stream statistics when
{{S3AInputStream#unbuffer}} is called.
