---------------------------------

             Summary: Default value of "lens.client.query.poll.interval" is 
very small
                 Key: LENS-978
                 URL: https://issues.apache.org/jira/browse/LENS-978
             Project: Apache Lens
          Issue Type: Improvement
            Reporter: Puneet Gupta
            Assignee: Puneet Gupta
            Priority: Trivial


The  poll interval is kept at 10 ms as of now . This causes excessive polling 
on the server (as most clients do not set the property to an optimum value). 

One use case for such small value could be in a case where user wants 
realtime/interactive response for queries that spend very small time in 
execution. But in this case the user has better options available in form of 
"EXECUTE_WITH_TIMEOUT" rather than using async query execution followed by 
continuous polling for state.

Further the EXECUTE_WITH_TIMEOUT will also be made available on CLI (which was 
not the case earlier) via LENS-915 

Propose to increase the value to 5 secs ( for specific use cases, users can 
override this value if required)
