Hi, We upgraded our prod cluster from HDP 2.3 to HDP 2..5 and after few days we have been getting new errors which never got in our former cluster. suddenly our zookeeper sever went down then we saw log "maximum client connection reached 60" then we changed the attribute to 200 in zoo.cfg. Again that host reached the max connection that is 200. So I dont understand why its hitting maximum connection everytime.
