Siddharth Seth commented on HIVE-16343:
---------------------------------------
This look up can be quite expensive. e.g. the SMAPS based lookup can take
multiple seconds. I don't think refreshing it every 10s is a good idea. Need to
have some kind of guard around when it gets refreshed (independent of the
metrics config)
