----------------------------------
Summary: FlinkYarnSessionCli with recovery enabled fails when
killing TaskManager
Key: FLINK-2969
URL: https://issues.apache.org/jira/browse/FLINK-2969
Project: Flink
Issue Type: Bug
Components: Distributed Runtime, YARN Client
Affects Versions: 0.10
Reporter: Ufuk Celebi
I'm running a YARN session with 2 physical nodes and 5 containers
(ApplicationMaster and 4 TaskManagers). There is no Flink program submitted to
the cluster.
Running a sequence of failure operations (killing the ApplicationMaster and
TaskManager containers), I sometimes get the following Exception after killing
a TaskManager:

I would like to investigate this for the 0.10.1/1.0 release and not block the
current RC.
