Change subject: IMPALA-13932: Add file path and position-based duplicate check for IcebergMergeNode ...................................................................... IMPALA-13932: Add file path and position-based duplicate check for IcebergMergeNode IcebergMergeNode's duplicate checking mechanism was based on comparing pointers of the target table's rows. This mechanism results in false positives if a new row batch reused the memory of the previous row batch provided for the merge node. This change adds an additional check that validates the file position and file path as well.
