Adam Kramer commented on HIVE-478: ---------------------------------- Also, in case it was not obvious, the current system counts time going by while mappers/reducers are "pending." This request would tell me how much time I actually used, e.g., not include time spent waiting for mappers or reducers. > Surface "processor time" for queries > ------------------------------------ > > Key: HIVE-478 > URL: https://issues.apache.org/jira/browse/HIVE-478 > Project: Hadoop Hive > Issue Type: Wish > Components: Logging, Query Processor > Reporter: Adam Kramer > > We currently list real-time metrics of how long queries take--"finished in: > 1min 13sec" appears on the job tracker. However, this is affected by a lot > more than just the quality or implementation of the query. For example, > number of mappers used varies a lot when you use subqueries versus > single-query aggregation, as does the amount of work necessary. > For implementation comparisons (e.g., "should I use this version of the query > or that one"), ti would be great to know the processor time used instead of > the real time used...both in terms of "mapper cpu seconds" and "reducer cpu > seconds." -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
