Subject [jira] [Commented] (HIVE-12952) Show query sub-pages on webui
Date Tue, 02 Feb 2016 14:29:39 GMT


Aihua Xu commented on HIVE-12952:

+1. The patch looks good.

Possible future improvement to consider:
1. In Perf-log tab, if we can add a total time for compile and execution, that could be helpful
for us to see if compile or execution has the bottleneck. 
2. The entries for compile stage should be divided into logical subtasks, like how much time
is spent on Parser, Logical Optimizer, Physical Optimizer, etc. And each of them can be divided
Semantic Analysis      50
Parser                        20
Optimizer                    50
Total                          5600

> Today the queries showing in Running and Completed lists have some basic information
like query string, elapsed time, state, user, etc.
> It may be helpful to have even more information like:
> * Job URL's, job status
> * Explain plan (configurable)
> * Error message (if failure)
> * Dynamic metrics, incl:
>  ** Number of Tables/partitions fetched
>  ** Time taken in each method via perf-logger.
> These should go in another page, so as not to clog the summary hiveserver.jsp page.
> This JIRA aims to tackle some of those.
