Thank you Jay. 1. I checked all host hdp-select, all versions are the same. 2. even if I find one out of sync, I dont know how to run this SELECT * FROM host_version; I guess I install oracle database for metadata, not mysql, please let me know if I am wrong. I just installed one more zookeeper, it allowed me to add new service. I know it dont make sense, but that is only thing I did. I think you provide all right answers. just let me know how to this query SELECT * FROM host_version; thank you again.

703-version.png please see the 'current 6/7', it means one of my hosts have issues, but I could not find any alert in my cluster and only warning in deploy.

703-version.png sorry, somehow it not uploaded last time. here it comes. please see current 6/7, one of my host do have issues, but I could not find any alert in any hosts in the cluster. I dont know how to query on ambari database, I did hdp-select, it is hard to compare the versions on each states on all hosts.

Please refer to this image of the current version 6/7, seemed one of my host has issues, but how to fix it?

Hi, I just installed a new HDP 2.5.3.0 cluster with 10 nodes, when I tried to 'add new service' it is in 'Loading....' and get no where. this is first time to my cluster, I have installed so many, never have this problem. I did all ambari-server restart, stop all service and start all service, also, chown root:root /var/run/ambari still not let me add new service. anyone have any ideas to help me here? thank you very much. Robin

Hi, gurus, I have kafka 3 nodes cluster and try to create a kafka connector to mongodb. I have followed this link, https://github.com/startappdev/kafka-connect-mongodb. Every step is ok, till create a connector by curl, curl -X POST -H "Content-Type: application/json" --data @/tmp/mongo_connector_configs.json http://localhost:8083/connectors an error after this: curl(7) connection refused. my port 8083 is not used by anyone on my localhost, I used 2181 for zeekeeper, 6667 for producer, what this 8083 does here? hope someone setup this before so can share some details with me. thank you very much. Robin
