pavibhai opened a new pull request #634: URL: https://github.com/apache/orc/pull/634
### What changes were proposed in this pull request? The following changes are proposed during the resolution of columns: * If a column is not found in the read schema, then fail with an `IllegalArgumentException` * If a column is not found in the file, then do not fail but instead treat as `NullReader` ### Why are the changes needed? In the absence of the patch, when the filter columns referred to missing columns in the file we were incorrectly getting an `IllegalArgumentException` instead of handling it as a missing column in the file. ### How was this patch tested? Unit tests were added to verify this behavior ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
