Subject [jira] Commented: (HIVE-30) Hive web interface
Date Wed, 24 Dec 2008 17:52:44 GMT


Edward Capriolo commented on HIVE-30:

Also I have ran into something that I would like to discuss. The ExecDriver produces this
output via printInfo()

Starting Job = job_200812241109_0004, Tracking URL = http://hadoop1:50030/jobdetails.jsp?jobid=job_200812241109_0004
Kill Command = /opt/hadoop/hadoop-0.19.0/bin/../bin/hadoop job  -Dmapred.job.tracker=hadoop1:54311
-kill job_200812241109_0004

I am trying to mimick this behaivor.

public String getJobTrackerURI(){
		StringBuffer sb = new StringBuffer();
		sb.append( conf.get("mapred.job.tracker.http.address") );
		return sb.toString();

This is not correct as HADOOPJOBNAME would actually be the HQL query. 

With the SessionState you can not reference SessionState->ExecDriver->JobConf. The only
way I can determine this information is by not letting the session be silent and reading/parsing
raw data. My usage of SessionState is a bit different then the current CLI session state.
A fix would be to have the exec driver set a read only HashMap in the Session State.

> 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.
