Hello, just happened again on our development cluster (RHEL 7.3). In this case reinstalling the cluster is not feasible. All my agents are version: ambari-agent-2.6.0.0-267.x86_64. My ambari-server: ambari-server-2.6.0.0-267.x86_64 A bit of context, I reached this point of the ambari upgrade procedure: https://docs.hortonworks.com/HDPDocuments/HDF3/HDF-3.0.2/bk_ambari-upgrade/content/upgrade_ambari.html After accessing the console I noticed Zookeeper, Storm and metrics were down (this is not correct, the services are running). Restarting zookeeper led to this error: stderr: /var/lib/ambari-agent/data/errors-1202.txt Traceback (most recent call last):

I tried upgrading the management pack after, but didn't help. In this case, should I open a JIRA?
