---------------------------------------
Summary: S3AInputStream to handle reconnect on read() failure
better
Key: HADOOP-15216
URL: https://issues.apache.org/jira/browse/HADOOP-15216
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.0.0
Reporter: Steve Loughran
{{S3AInputStream}} handles any IOE through a close() of stream and single
re-invocation of the read, with
* no backoff
* no abort of the HTTPS connection, which is just returned to the pool, If
httpclient hasn't noticed the failure, it may get returned to the caller on the
next read
Proposed
* switch to invoker
* retry policy explicitly for stream (EOF => throw, timeout => close, sleep,
retry, etc)
We could think about extending the fault injection to inject stream read
failures intermittently too, though it would need something in S3AInputStream
to (optionally) wrap the http input streams with the failing stream.
