> Some events in the YARN container entities have timestamp of -1. The RM-generated container events have proper timestamps. It appears that it's the NM-generated events that have -1: YARN_CONTAINER_CREATED, YARN_CONTAINER_FINISHED, YARN_NM_CONTAINER_LOCALIZATION_FINISHED, YARN_NM_CONTAINER_LOCALIZATION_STARTED.
> In the YARN container page,

> {
> id: "YARN_CONTAINER_CREATED",
> timestamp: -1,
> info: { }
> },
> {
> id: "YARN_CONTAINER_FINISHED",
> timestamp: -1,
> info: {
> YARN_CONTAINER_EXIT_STATUS: 0,
> YARN_CONTAINER_STATE: "RUNNING",
> YARN_CONTAINER_DIAGNOSTICS_INFO: ""

> I think the data itself is OK, but the values are not being populated in the REST output?
