> -----------------------------------------------------------------------------------------
>
> Key: PARQUET-295
> URL: https://issues.apache.org/jira/browse/PARQUET-295
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: 1.6.0
> Reporter: Tim Chan
> Priority: Minor
> Labels: filter2
>
> When using both filter predicate and projection pushdown of columns, the
> column specified in the filter predicate, should not have to be specified in
> the projection pushdown.
> For example, if I want the first names of students that are over the age of
> 16, then I should be able to specify
> ParquetInputFormat.setFilterPredicate(jobConf, IntColumn("age") > 16) and
> only have to specify ThriftReadSupport.setProjectionPushdown(jobConf, "fname")
