[jira] [Updated] (NIFI-9559) Zookeeper Client Can't Reconnect - Session timeout has elapsed while SUSPENDED

     [ https://issues.apache.org/jira/browse/NIFI-9559?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shawn Weeks updated NIFI-9559:
------------------------------
    Description: 
After a loss of connection to Zookeeper a NiFi node never successfully reconnects to the Zookeeper or the Cluster and instead returns errors about no Cluster Coordinator and a Session timeout has elapsed while SUSPENDED repeatedly until you restart NiFi.

The error described is the same one at https://issues.apache.org/jira/browse/CURATOR-405 however that patch has been in NiFi for several versions now.

NiFi version is 1.15.3 and Zookeeper 3.6.3

  was:
It's possible this is fixed in 1.15.2 but I don't see any commits that would have resolved it. After a loss of connection to Zookeeper a NiFi node never successfully reconnects to the Zookeeper or the Cluster and instead returns errors about no Cluster Coordinator and a Session timeout has elapsed while SUSPENDED repeatedly until you restart NiFi.

The error described is the same one at https://issues.apache.org/jira/browse/CURATOR-405 however that patch has been in NiFi for several versions now.

NiFi version is 1.14.0 and Zookeeper 3.6.3
