[jira] [Updated] (LENS-1262) Support adding Driver Completion Listener after rewrite and estimate operation(and before submit)

     [ https://issues.apache.org/jira/browse/LENS-1262?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Puneet Gupta updated LENS-1262:
-------------------------------
    Description: 
LensDriver#registerDriverEventListener will not be reliable if its added after queuing/submitting the query. This is because split sec queries an finish and immediate failures can happen even before one is able to call registerDriverEventListener of driver and in this case events are lost.

As of now registerDriverEventListener is being done after submitting the query.  We should support pre submit listener additions
