[jira] [Resolved] (AVRO-2286) DataFileReader leaks file descriptor
on exception during construction
[ https://issues.apache.org/jira/browse/AVRO-2286?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Kulp resolved AVRO-2286.
-------------------------------
Resolution: Fixed
Fix Version/s: 1.9.0
> DataFileReader leaks file descriptor on exception during construction
> ---------------------------------------------------------------------
>
> Key: AVRO-2286
> URL: https://issues.apache.org/jira/browse/AVRO-2286
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Affects Versions: 1.8.2
> Reporter: Holger Fleischmann
> Assignee: Martin Jubelgas
> Priority: Major
> Fix For: 1.9.0
>
> Attachments: DataFileReaderCloseBug.java
>
>
> The constructor {{DataFileReader(File, DatumReader)}} does not close the already opened file again when it throws an exception. This leads to a leaked file descriptor and especially to not being able to delete the still open invalid file then (at least on Windows).
> This case is important when Avro files may be truncated on write, e.g. due to a hard shutdown, and the application must be able to recover from such a situation on the next restart.
> Please see the attached file {{DataFileReaderCloseBug.java}} to reproduce the problem.
> I did not find that problem in Jira/mailing lists. Thanks for your help in advance :)
