             Summary: Fix native services API JsonMappingException for PlacementPolicy
                 Key: YARN-5985
                 URL: https://issues.apache.org/jira/browse/YARN-5985

          Issue Type: Sub-task
            Reporter: Billie Rinaldi
            Assignee: Gour Saha


I tried setting placement_policy in the native services API and got the following exception:

{noformat}
{"exception":"JsonMappingException","message":"Can not instantiate value of type [simple type,
class org.apache.hadoop.yarn.services.resource.PlacementPolicy] from JSON String; no single-String
constructor/factory method (through reference chain: org.apache.hadoop.yarn.services.resource.Application[\"components\"]->org.apache.hadoop.yarn.services.resource.Component[\"placement_policy\"])","javaClassName":"org.codehaus.jackson.map.JsonMappingException"}
{noformat}
