>                 Key: HIVE-1648
>                 URL: https://issues.apache.org/jira/browse/HIVE-1648
>             Project: Hadoop Hive
>          Issue Type: Sub-task
>            Reporter: Ning Zhang
> 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).
