--------------------------------------------
Summary: Handle orphaned Yarn containers in Gobblin-on-Yarn
clusters
Key: GOBBLIN-1099
URL: https://issues.apache.org/jira/browse/GOBBLIN-1099
Project: Apache Gobblin
Issue Type: Improvement
Components: gobblin-yarn
Affects Versions: 0.15.0
Reporter: Sudarshan Vasudevan
Assignee: Abhishek Tiwari
Fix For: 0.15.0
A Yarn application may leave behind orphaned containers, which can happen due
to lost node managers. The orphaned containers however can continue to run
(potentially forever) as participants in the Helix cluster. This can cause the
following problems for a Gobblin-on-Yarn application:
# Double publish of data and commit of state
# Task failures and partition starvation during application restarts, as Helix
may assign tasks to the orphaned containers which have a stale state and
configuration
# Container failures on application restarts due to Helix instance name
collisions with orphaned containers
