------------------------------
Summary: Deletion Taks will be picked up to delete running
containers
Key: YARN-9192
URL: https://issues.apache.org/jira/browse/YARN-9192
Project: Hadoop YARN
Issue Type: Bug
Components: applications
Affects Versions: 2.9.1
Reporter: Sihai Ke
I suspect there is a bug in Yarn deletion task service, below is my repo steps:
# First let's set yarn.nodemanager.delete.debug-delay-sec=3600, that means
when the app finished, the Binary/container folder will be deleted after 3600
seconds.
# when the application App1 (long running service) is running on machine
machine1, and machine1 shutdown, ContainerManagerImpl#serviceStop() will be
called -> ContainerManagerImpl#cleanUpApplicationsOnNMShutDown, and
ApplicationFinishEvent will be sent, and then some delection tasks will be
created, but be stored in DB and will be picked up to execute 3600 seconds.
# 100 seconds later, machine1 comes back, and the same app is assigned to run
this this machine, container created and works well.
# then deleting task created in step 2 will be picked up to delete containers
created in step 3 later.
