---------------------------------
Summary: Yarn session CLI tries to shut cluster down too
agressively in interative mode
Key: FLINK-6152
URL: https://issues.apache.org/jira/browse/FLINK-6152
Project: Flink
Issue Type: Bug
Components: Client
Affects Versions: 1.2.0, 1.3.0
Reporter: Yelei Feng
Once yarn session CLI can't get cluster status, it shuts the cluster down and
cleanup related files even if new jobmanger will be created soon. As result, AM
restarting will fail due to missing files on HDFS
reproduce step:
1. start yarn session in interactive mode
2. kill jobmanager process
3. yarn session client can't get cluster status in lookup time and hence
trigger shutdown hook which would delete local properties files and files on
HDFS, but it can't shutdown the cluster since it can't connect to jobmanager.
