---------------------------------
Attachment: YARN-10810-001.patch
> YARN Native Service Definition is not backward compatible

> Key: YARN-10810
> URL: https://issues.apache.org/jira/browse/YARN-10810
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn-native-services
> Affects Versions: 3.3.0
> Reporter: Prabhu Joseph
> Assignee: Prabhu Joseph

> YARN Native Service Spec PlacementScope value was *NODE* in hadoop-3.1
> version but got changed to *node* in hadoop-3.3. This causes older Service
> Client (hadoop-3.1) to fail while getting the status from new Api Server
> (hadoop-3.3). This looks caused due to jackson upgrade.
