I have followed the given link https://community.hortonworks.com/articles/149376/metron-model-as-a-service-maas-full-dev-platform.html I have completed deployment up to Step 5 but facing issues in step 6. 1. I have made adjustments in squid configurations to call Model. 2. When I am sending data to squid topic the storm topology shows this error “java.lang.RuntimeException: org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /metron/topology/global at org.apache.metron.common.bolt.ConfiguredBolt.” 3. when I have checked the zookeeper logs it shows “2019-04-03 16:30:27,943 - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@193] - Too many connections from /xxx.xxx.xx.xxx- max is 60 2019-04-03 16:30:30,039 - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@193] - Too many connections from / xxx.xxx.xx.xxx - max is 60 2019-04-03 16:30:31,769 - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@193] - Too many connections from / xxx.xxx.xx.xxx - max is 60” And zookeeper also shows alert “Connection failed: [Errno 104] Connection reset by peer to xxx.xxx.xxx:2181”
