Kevin Risden commented on KNOX-1524: ------------------------------------ I sent a message to the Hive user list to see if there are any recommendations about making HiveServer2 perform better in HTTP mode. > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
