--------------------------------
Summary: C++ reader for direct string encodings occasionally skips
bytes
Key: ORC-24
URL: https://issues.apache.org/jira/browse/ORC-24
Project: Orc
Issue Type: Bug
Components: C++
Reporter: Owen O'Malley
Assignee: Owen O'Malley
Fix For: 1.0.0
The ORC C++ direct string column reader can occasionally skip bytes in the blob
stream.
The necessary conditions are:
* The column is a string column and is directly encoded.
* The blob stream for the row batch crosses a compression block boundary.
* There is a null value toward the end of the block boundary.
* The value in the length value of the null value crosses the block boundary,
but the length value of the following value does not.
