             Summary: HiveServer should pick AMs which are already ready from the pool
                 Key: HIVE-13158
                 URL: https://issues.apache.org/jira/browse/HIVE-13158
             Project: Hive
          Issue Type: Bug
            Reporter: Siddharth Seth


Scenario. Start HiveServer2 with 3 sessions. At startup there's capacity for this.
All 3 sessions time out.
There's capacity for one session only.
The first query submitted will start a session and use it.
The second query submitted (after the first one is submitted) ends up trying to launch a new
session as well - instead of using the existing free session. Since there's no capacity, this
ends up blocking.
