Tim Armstrong resolved IMPALA-1874.
-----------------------------------
    Resolution: Won't Do

I don't think we want to introduce this kind of complexity.

>                 Key: IMPALA-1874
>                 URL: https://issues.apache.org/jira/browse/IMPALA-1874
>             Project: IMPALA
>          Issue Type: Improvement
>          Components: Perf Investigation
>    Affects Versions: Impala 2.1.1, Impala 2.2
>            Reporter: Bharath Vissapragada
>            Priority: Trivial
>              Labels: hbase, performance
>
> Currently all hbase scans go via hbase's Scan api. However for static tables it might be much quicker to directly read the HFiles, something like HFileInputFormat in hive. This avoids entire RS stack and gives much better performance.
