Subject [jira] Commented: (HADOOP-4514) Hive web interface
Date Mon, 27 Oct 2008 20:55:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4514?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12643055#action_12643055

Edward Capriolo commented on HADOOP-4514:

Inside Hadoop components like NameNode implement HttpServlet directly. 

I think we should replicate the bin/hive to bin/hiveweb this would kick off a management application.

$hadoop/webapps/hiveweb would be the home for the JSP files

I think we should have a Threaded application running inside the servlet engine. 

If a user runs a query that would have output to the console we should save that data into
temporary file?
If so where would that data be save?
How long before if should be cleaned up?
If it creates a temporary file should we impose a limit on the size? Select * could be really
big where would that
local data go?

We could offer a browse of the database by using the meta information and the HDFS files directly?
A simple Next 100 Previous 100.

>             Project: Hadoop Core
>          Issue Type: New Feature
>          Components: contrib/hive
>            Reporter: Jeff Hammerbacher
>            Priority: Minor
> Hive needs a web interface. The initial checkin should have:
> * simple schema browsing
> * query submission
> * query history (similar to MySQL's SHOW PROCESSLIST)
> A suggested feature: the ability to have a query notify the user when it's completed.
> Edward Capriolo has expressed some interest in driving this process.
