--------------------------------------------
Summary: Track unused Helix instances in a thread-safe manner
Key: GOBBLIN-1211
URL: https://issues.apache.org/jira/browse/GOBBLIN-1211
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
The AMRMClient processes container allocation events asynchronously in a
separate thread. If there are multiple concurrent container requests and
consequent callbacks, we need to ensure that updates to shared data structures
such as the set of unused Helix instance names are consistent and thread-safe.
In other words, any updates to this set made by one thread will be visible to
all other threads handling the container allocation events.
