Yiheng Wang commented on LIVY-515: ---------------------------------- This is reported in 0.4.0. Maybe this issue has been fixed in latest version. > Livy session is idle even if spark context is unavailable > --------------------------------------------------------- > > Key: LIVY-515 > URL: https://issues.apache.org/jira/browse/LIVY-515 > Project: Livy > Issue Type: Bug > Components: Core > Affects Versions: 0.4.0 > Reporter: Raghavendra > Priority: Major > Attachments: AfterKillingLivy.png, BeforeKillingLivy.png, > command.history, livy-log, livyUI.png > > > When using livy in the session mode, Livy is not able to figure out if the > application master is available. > Say suppose livy was in the idle state, now for some reason the application > master died. Ideally, even the session associated with this application > master should either be terminated or should have handled this situation. > Instead, the session continues to remain in the Idle state. This is wrong. > > Steps to reproduce. > # Bring up livy in session mode(I am using 5 sessions). > # Kill the application master using "yarn application -kill <application id>" > # Now list the application in yarn "yarn application -list" you will see 4 > application master(I had 5, Killed 1 so 4) > # Now reload livy UI. You will still see 5 sessions in idle. > Attached the session logs whose application master was killed. > Attached are some images depicting the issue -- This message was sent by Atlassian Jira (v8.3.2#803003)
