Key: ORC-980
URL: https://issues.apache.org/jira/browse/ORC-980
Project: ORC
Issue Type: Bug
Components: Java
Affects Versions: 1.7.0, master
Reporter: Pavan Lanka

The current SArg to Filter Conversion ignores the case-sensitivity setting
during read and always perform case-sensitive search of fields leads to
exceptions such as
{quote}java.lang.IllegalArgumentException: Field RIDX not found in
struct<f1:bigint,f2:decimal(20,6),f3:bigint,f4:string,ridx:bigint>

This needs to change instead to respect the configuration passed down via the
reader options.
