Hi all,
I just found CacheController.announceWipeCache() method was invoked every
minitue on my kylin query server. i added some log(IP:10.62.22.95 is my query
server ip) and found it's invoked by the query server itself. i search the
whole project and can't find the source. i don't think it's normal to invoke
announceWipeCache every minitue. could you tell why it's invoked so often?
thanks.
below is my server log:
