Can you send it to me - I will add you as a hive contributor.
Also, can you 'Submit Patch' when you add a patch - this way everyone knows

> HIVE-1361 introduces a new command 'ANALYZE TABLE T COMPUTE STATISTICS' to
> gathering stats. This requires additional scan of the data. Stats gathering
> can be piggy-backed on TableScanOperator whenever a table/partition is
> scanned (given not LIMIT operator).
