[jira] [Created] (LENS-1164) Query getting stuck in queue for inmemory queries

Archana H created LENS-1164:
-------------------------------

             Summary: Query getting stuck in queue for inmemory queries
                 Key: LENS-1164
                 URL: https://issues.apache.org/jira/browse/LENS-1164
             Project: Apache Lens
          Issue Type: Bug
            Reporter: Archana H


Scenario:
Max concurrent set to 1 and both persistence is false.
3 queries are fired. 1 goes to running, rest 2 queued.
Even after 1st query is purged (after crossing TTL time), queries from queued are not getting picked for running. Any new query fired is getting completed, but those 2 are stuck in queue.

This is happening because queries gets picked from waiting queue only upon query completion but in this case query is already completed.
But when new query is fired and it completes, queries in waiting queue should be considered for running which is not happening in this case.
