Deepak Majeti created ORC-58:
--------------------------------
Summary: Simplify ReaderImpl constructor and create a new Open
method
Key: ORC-58
URL: https://issues.apache.org/jira/browse/ORC-58
Project: Orc
Issue Type: Improvement
Components: C++
Reporter: Deepak Majeti
Existing ReaderImpl constructor can throw an exception. This prohibits the
creation of the reader instance and subsequent access to the schema information.
For instance, an exception can be thrown if the selected column ids do not
agree with the number of schema columns. The downstream application might still
want the schema information for logging purposes.
The scope of this Jira is to simplify the ReaderImpl constructor and move most
of the logic to a new "Open" method.
