> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: yarn-native-services

> Reporter: Gour Saha

> This is easy to test on a service with anti-affinity component, to simulate
> pending container requests. It can be simulated by other means also (no
> resource left in cluster, etc.).
> Service yarnfile used to test this -
> {code:java}
> {
> "name": "sleeper-service",
> "version": "1",
> "components" :
> [
> {
> "name": "ping",
> "number_of_containers": 2,
> "resource": {
> "cpus": 1,
> "memory": "256"
> },
> "launch_command": "sleep 9000",
> "placement_policy": {
> "constraints": [
> {
> "type": "ANTI_AFFINITY",
> "scope": "NODE",
> "target_tags": [
> "ping"
> ]
> }
> ]
> }
> }
> ]
> }
> {code}
> Launch a service with the above yarnfile as below -
> {code:java}
> yarn app -launch simple-aa-1 simple_AA.json
> {code}
> Let's assume there are only 5 nodes in this cluster. Now, flex the above
> service to 1 extra container than the number of nodes (6 in my case).
> {code:java}
> yarn app -flex simple-aa-1 -component ping 6
> {code}
> Only 5 containers will be allocated and running for simple-aa-1. At this
> point, flex it down to 5 containers -
> {code:java}
> yarn app -flex simple-aa-1 -component ping 5
> {code}
> This is what is seen in the serviceam log at this point -
