Can you post the logs from zookeeper to see? Also, can you publish the difference in config changes between before upgrade and now by looking at Ambari config history and comparing the two? Even a screenshot will do there. Btw, make sure logs are clear of any site specific information as this is a public forum.</P> Fri, 10 Feb 2017 01:12:09 GMT aervits 2017-02-10T01:12:09Z
