Edward Capriolo commented on HIVE-3307:
---------------------------------------
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.

>
> 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 * add a way to know if the result bucket is outdated (ie for which run, those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)
