---------------------------------------
Summary: s3a: set fs.s3a.downgrade.syncable.exceptions = true by
default
Key: HADOOP-17928
URL: https://issues.apache.org/jira/browse/HADOOP-17928
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.3.1
Reporter: Steve Loughran
Assignee: Steve Loughran
HADOOP-17597 set policy of reacting to hsync() on an s3 output stream to be one
of :Fail, warn, with default == fail.
I propose downgrading this to warn. We've done it internally, after having it
on fail long enough to identify which processes were doing either of
* having unrealistic expectations about the output stream (fix: move off s3)
* were using hflush() as a variant of flush(), with the failure being an
over-reaction
