NiFi connected via WebUI but without communication with CM

[#1]

In the development cluster, the NiFi nodes do not show data or connection to Cloudera Manager, but if I access them via WebUI, the nodes appear properly connected and functional. Attached are NiFi logs and screen prints as evidence Previously I was instructed to review the Ranger policies as described in the Cloudera documentation, but the problem persisted, attached are the current Ranger settings. I also found the following error curious: Cookie rejected [hadoop.auth=""u=nifi&p=nifi/[email protected]&t=kerberos&e=1721689709429&s=qJPbU6hDNqLtkL1BokMp...", version:0, domain:v321d175.prevnet, path:/solr/ranger_audits_shard1_replica_n1, expiry:null] Domain attribute "v321d175.prevnet" violates the Netscape cookie specification However, in the prod cluster the same error appears in the logs and I don't have this problem

If I understand correctly,  Service NiFi works fine but from the Cloudera Manager things do not look promising this has to do with how CM monitors the NiFI service 

I would start to at the logs directory under the NiFi processor directory on each host where niFi is running and look for file connectionMetricOutput.log 

NNNNNNNN-nifi-NIFI_NODE/logs/connectionMetricOutput.log

On each Node where NiFi service is running, CM agent invokes nifi cli command get-nodes to get the health status of each node.

bin/cli.sh nifi get-nodes

If you find get-nodes command is not completing, you may want to further file a support case with us to look in detail. 

I hope this helps.

Thank you

Hi @ckumar ,

I couldn't find the command, would it be in the parcels path as shown in the attached printout?
