[jira] [Created] (LENS-1527) Fix session restore issue

Barun Kumar created LENS-1527:
---------------------------------

             Summary: Fix session restore issue
                 Key: LENS-1527
                 URL: https://issues.apache.org/jira/browse/LENS-1527
             Project: Apache Lens
          Issue Type: Bug
          Components: api, server
            Reporter: Barun Kumar
            Assignee: Barun Kumar


When a session is created in Lens, corresponding hive session is created for cluster user and session count map for user is updated. But when Lens is started and restores it's sessions, the session count map is updated for cluster user.

 

Since many user may have same cluster user, on restart of Lens the session count for cluster user will be a lot and if you try to create session using that cluster user, you might get 429(which is sent when session limit is exhausted for a user).

The fix for this is while resotring the session, use loggedin user to update the session count map.
