vvysotskyi opened a new pull request #1552: DRILL-6865: Query returns wrong result when filter pruning happens URL: https://github.com/apache/drill/pull/1552 This PR contains two commits: - The first commit contains changes to preserve predicates from filter condition which weren't used for filter pushdown to avoid the case when the filter is pruned. Instead of pruning whole the filter, only predicates which were used in the row group filtering are removed. Please note, that this problem happened only for the case when row group fully matches to the predicates which are used in the filter pushdown. - The second commit contains changes to remove filter from the plan when parquet table has a single row group and fully matches the filter. For problem descriptions please see [DRILL-6865](https://issues.apache.org/jira/browse/DRILL-6865).
