Yesha Vora created YARN-8579:
--------------------------------
Summary: New AM attempt could not retrieve previous attempt
component data
Key: YARN-8579
URL: https://issues.apache.org/jira/browse/YARN-8579
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 3.1.1
Reporter: Yesha Vora
Steps:
1) Launch httpd-docker
2) Wait for app to be in STABLE state
3) Run validation for app (It takes around 3 mins)
4) Stop all Zks
5) Wait 60 sec
6) Kill AM
7) wait for 30 sec
8) Start all ZKs
9) Wait for application to finish
10) Validate expected containers of the app
Expected behavior:
New attempt of AM should start and docker containers launched by 1st attempt
should be recovered by new attempt.
Actual behavior:
New AM attempt starts. It can not recover 1st attempt docker containers. It can
not read component details from ZK.
Thus, it starts new attempt for all containers.
