-------------------------------------------
Summary: Fail fsync immediately
Key: LUCENE-6902
URL: https://issues.apache.org/jira/browse/LUCENE-6902
Project: Lucene - Core
Issue Type: Improvement
Reporter: Daniel Mitterdorfer
Priority: Minor
While analysing a build issue in Elasticsearch I stumpled upon
org.apache.lucene.util.IOUtils.fsync. It has a retry loop in fsync whenever an
IOException occurs. However, there are lots of instances where a retry is not
useful, e.g. when a channel has been closed, a ClosedChannelException is thrown
and IOUtils#fsync still tries to fsync multiple times on the closed channel.
After bringing the issue to Robert's attention, he even opted for removing the
retry logic entirely for fsyncing.
