---------------------------------------
Summary: S3ABlockOutputStream.flush() be no-op when stream closed
Key: HADOOP-15239
URL: https://issues.apache.org/jira/browse/HADOOP-15239
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.0.0, 2.7.5, 2.8.3, 2.9.0
Reporter: Steve Loughran
when you call flush() on a closed S3A output stream, you get a stack trace.
This can cause problems in code with race conditions across threads, e.g.
FLINK-8543.
we could make it log@warn "stream closed" rather than raise an IOE. It's just a
hint, after all.
