[jira] [Created] (HIVE-3307) Hive Web Interfaces Wishes
Bertrand Dechoux created HIVE-3307:
--------------------------------------
Summary: Hive Web Interfaces Wishes
Key: HIVE-3307
URL: https://issues.apache.org/jira/browse/HIVE-3307
Project: Hive
Issue Type: Wish
Components: Web UI
Reporter: Bertrand Dechoux
Priority: Minor
List of wishes :
(I may contribute a few of them.)
* narrower menu : use span2 instead of span4
* remove home from menu
* transform the header "Hive Web Interface" into a link to the home
* change the "Link" in the header into a hive logo
* add icons next to Authorize (?/check) to know whether the information was supplied
* add approximated number of session next to the "list sessions" menu
* fix history bug
* add a refresh session in order to have a relatively updated interface
* add a way to know if the result bucket is outdated (ie for which run, those results are related)
* change the with of the query input, it should be width:100%
* remove select/drop down for running query and use a button instead
* remove select/drop down for silent mode and add a checkbox
* find a way to report query error (hack would be with explain command, is there something only checking the syntax)
* table description : decorate all key/value entries and do not display empty list

----------------------------------------
I have done tests with the CLI. Explain is quite fast when there is a syntax error and longer when it need to really explain. I was wondering are these two steps separated as of now? Would I be able to call only the first one?
(That won't be the first thing I will look at because I will first need to learn a bit about the hive implementation but I am curious.)

---------------------------------------
The explain is not two parts it is a normal query processed by the query parser. The reason it is 'faster' if the query is wrong is because the parsing happens first, if there is a parse error less work is done, if it passes the parsing phase it has more work to do, some of that work involves communicating with the metastore so that will take longer. Generally I see explain take a couple of seconds.If there was a window with an hourglass type thing that let me the user know to wait for result I thing an async call is fine.
You could probably just get at the parser and try to parse the query quickly but as far as I know there is no direct way to do that now.

All good stuff. I would like to see the explain the most since explains run fast we should be able to take the query put an 'explain ' in front and then rung that in separate window (or popup in a blocking fashion) that would be a nice feature.
