--------------------------------------
Sorry, I had a transitive dependency bringing in 1.4.0, I have verified that
this is fixed in 1.5.1.
Thanks much for looking into it!

> Key: AVRO-828
> URL: https://issues.apache.org/jira/browse/AVRO-828
> Project: Avro
> Issue Type: Improvement
> Components: java
> Affects Versions: 1.5.1
> Environment: Java 1.6
> Reporter: Douglas Britsch
> Labels: empty, file, header, marker, sync
> Fix For: 1.5.1
>
>
> When opening an avro file to be written, the 16-byte, sync marker for file
> not generated till first record written or the file properly closed. Our
> usecase has the logs being rotated if they have no open filehandles which
> means if we open a file and experience an unclean shutdown we get files that
> throw exceptions on processing. When records are written the sync marker is
> written on each write which prevents this from being a problem on non-empty
> files. Can we write the sync marker when the header is written instead of on
> first record write?
