In my case catalogd listens on ports 23020, 25020 and 26000. Also everything seems to be working fine. I can see this subscriber in the StateStore UI: Id: catalog-server@hostname:26000 Address: hostname:23020 And also in the Catalog Server UI: statestore-subscriber.connected = true So it really appears that the check is producing false positive, but I don't know how to debug it. It will be helpful if anyone can give a hint in which log to look to find why the check is failing.

The cluster is now running CM/CDH 5.7.1 and the Catalog Server Connectivity Health Test is still showing This Catalog Server is not connected to its StateStore. I am keeping the check disabled, but I enabled it temporarily to see if the issue has been resolved. It appears to be a rare issue because searching in Google doesn't help.

Hello, One of our clients is running Cloudera Manager Express 5.3.2 and CDH 5.3.2. There is a strange problem with the Impala Catalog Server. It has Bad Health in Cloudera Manager which shows the following messages: StateStore Connectivity Bad This Catalog Server is not connected to its StateStore. I can't find anything useful in the log files of the Catalog Server or the StateStore. Also everything seems to be working properly and the metadata changes are relayed successfully (I performed several tests using 2 different Data Nodes). In the StateStore Web UI I can see the Catalog Server in the list of the subscribers. Id: catalog-server@hostname:26000 Address: hostname:23020 Subscribed topics: 1 Transient entries: 0 If I stop the Catalog Server this entry disappears so it is not a stale one. I even tried to delete the whole Impala Service and install it again using different node for the StateStore and the Catalog Server. However nothing seems to be helping. Kerberos and SSL are not used in the cluster. I suspect that there is only a problem with the Cloudera Manager health check but I have no idea how to troubleshoot further Please let me know if you have any suggestions. Best Regards, Cyril
