Puneet Gupta commented on LENS-1227:
------------------------------------


lens.server.query.http.notifictaion.urls = comma separated urls 

All notifictions will have user, query_id (and query name if any). Apart from 
this deault info will be shared for each STATE . 
Extra info can be requested too

**lens.server.query.http.notication.types = (QUEUED,RUNNING,*FINIHSED) 
**lens.server.query.http.notication.type.finished.info = 
(*STATUS,RESULT,TOTALRUNTIME,TOTALWAIT,etc) 
**lens.server.query.http.notication.type.queued.info = 
(*QUEUENUMBER,PRIORITY,etc)
**lens.server.query.http.notication.type.running.info = (TOTALWAIT,etc)
**lens.server.query.http.notifictaion.retries = 2 (Default is 0)

**=  not mandatory
*= Default option

> Support HTTP notification for query STATE changes

> 1. HTTP notofication for different stages of query execution 
> -- QUEUED
> -- RUNNING
> -- FINISHED
> 2. Support default info for each state
> 3. Suppoort extra info for each state 
> 4. Support retries
> 5. Support enabling notification by defult for a driver type and state (say 
> for hive queries since they take longer and all STATE updates would be nice)
> 6. Support progress updates in RUNNING state (esp. useful for loing running 
> queries). This will make sense only when progress number is accurate.
