> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Reporter: Michael Smith
> Assignee: Michael Smith
> Priority: Major
>
> TranslateColPaths() can legitimately return an empty
> table_col_path/file_col_path pair: when the table is full ACID but the
> underlying file is not, and col_path refers only to the synthetic ACID "row"
> pseudo-column, neither schema has a corresponding node, so nothing is pushed
> to either output path. ResolveColumnByName() does not account for this and
> unconditionally indexes table_path[0], reading out of bounds on the empty
> vector
