------------------------------------
dongjoon-hyun opened a new pull request #320: ORC-416: Avoid opening data
reader when there is no stripe
URL: https://github.com/apache/orc/pull/320
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.
```
this.dataReader.open();
```
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.
