------------------------------------
KNOX-1530 is mostly done so can come back to test this further over the next
few days.
> Hive "select *" performance evaluation

> Key: KNOX-1524
> URL: https://issues.apache.org/jira/browse/KNOX-1524
> Project: Apache Knox
> Issue Type: Task
> Reporter: Kevin Risden
> Assignee: Kevin Risden
> Priority: Major
> Fix For: 1.2.0
>
>
> While looking at WebHDFS performance in KNOX-1221, I decided to look a bit
> more into performance for common use cases. Hive performance is another area
> that could use some research.
> Use "select * ... limit" to get a comparison of raw return speed from
> HiveServer2. This should show how fast results can be streamed through
> HiveServer2 and Knox. Compare the results to "hdfs dfs -text" since this will
> render the data directly from HDFS. This should give comparisons for the
> difference in overhead between HDFS, HiveServer2 binary, HiveServer2 HTTP,
> and HiveServer2 HTTP with Knox.
