Kevin Risden commented on KNOX-1524: ------------------------------------ h2. Result Interpretation HiveServer2 adds quite a bit of overhead compared to reading the file directly from HDFS. Binary mode of HiveServer2 is more efficient than HTTP mode. The Knox overhead is minimal compared to the HiveServer2 overhead. There are probably some improvements that can be made to HiveServer2 to improve the performance. > 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.
