Dongjoon Hyun created ORC-416:
---------------------------------
Summary: 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: 1.5.3, 1.5.2, 1.5.1, 1.5.0
Reporter: Dongjoon Hyun
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.
