Owen O'Malley reassigned ORC-416:
---------------------------------
Assignee: Dongjoon Hyun
> Avoid opening data reader when there is no stripe
> -------------------------------------------------
>
> Key: ORC-416
> URL: https://issues.apache.org/jira/browse/ORC-416
> Project: ORC
> Issue Type: Bug
> Components: Java
> Affects Versions: 1.5.0, 1.5.1, 1.5.2, 1.5.3
> Reporter: Dongjoon Hyun
> Assignee: Dongjoon Hyun
> Priority: Major
>
> Currently, `RecordReaderImpl` invokes `dataReader.open` in the middle of the
> constructor. We can postpone this until `advanceToNextRow` reads the stripe
> at the end of the constructor.
> {code:java}
> this.dataReader.open();
> {code}
> This will reduce the chance of potential open-file leakages due to
> IOException and OOM during `RecordReaderImpl` construction. Also, we can
> avoid it completely when there is no stripe in the file.
