I sent a [message to the Hive user 
list|http://mail-archives.apache.org/mod_mbox/hive-user/201810.mbox/%3CCAJU9nmhgkHqOpP5TOC-c%3Dz7Bs_%2Br6KY7R9U%2B6qK6cH5Pvccr7g%40mail.gmail.com%3E]
 to see if there are any recommendations about making HiveServer2 perform 
better in HTTP mode.

> 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.
