>
> Key: ORC-1121
> URL: https://issues.apache.org/jira/browse/ORC-1121
> Project: ORC
> Issue Type: Bug
> Components: Java
> Affects Versions: 1.6.11
> Reporter: Penglei Shi
> Priority: Major
> Fix For: 1.6.14, 1.7.4
>
>
> RecordReaderImpl::pickRowGroups() will check if filter-column is safe for ppd
> evaluation with file column id, but the parameter of
> SchemaEvolution::isPPDSafeConversion is reader column id, which is different
> from file column id, and this causes pushed filters can't be evaluated and
> recordReader can't skip row groups which are not matched.
