Tim Armstrong created IMPALA-6267:
-------------------------------------

             Summary: MT Scanners do not check runtime filters per-file before processing each split
                 Key: IMPALA-6267
                 URL: https://issues.apache.org/jira/browse/IMPALA-6267
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
    Affects Versions: Impala 2.10.0
            Reporter: Tim Armstrong


The old implementation of HdfsScanNode re-checks partition filters per scan range in HdfsScanNode::ProcessSplit() before processing each scan range. HdfsScanNodeMt does not have similar logic.
