stale_status_of_NM_from_standby_RM

[Dong Ye]

Hi, All:

    I have some questions about the state of the node manager. If I use the
rest API

   - http://rm-http-address:port/ws/v1/cluster/nodes/{nodeid}

to get node manager state from a standby RM,
1) is it possible that it could be stale?
2) If it is possible, how long will the node manager state be updated?
3) Is it possible that the NM state returned from standby RM be very
different from that returned from the active RM? Say one is returning
RUNNING while the other returns DECOMMISSIONED because the local
exclude.xml is very different/diverges?

Thanks.
Have a good holiday.
