Details you can only get through UI or API , considering web endpoint is reachable, Seems in this case NiFi service is up but UI is not available or NiFi service is completely down , can be confirm by checking its process status. So you need find way to bring back the NIFI service along with UI in minimalistic load by stopping all flows by setting nifi.flowcontroller.autoResumeState to false and start the service, by doing this nifi will start with all the queued data but it will not do any processing, this can give you the UI but since you have said that are too much data so startup will take time.

The error says the Connection pool is not able to find configured driver classpath name into provided database client-jar driver. Please check and make sure configured driver classpath name is present on the provided jar file.

Thanks for taking the time to respond @ckumar Merge strategy is set to Defragment and yes it seems to be waiting for the remaining 2 files which never arrive. I have noticed that if a record isn't found in the Elastic index, QueryElasticSearchHTTP processor does not return a failure and so there is nothing returned through any relationship for the missing 2 records.

Thanks @ckumar @MattWho for your responses. I enabled session affinity on LB and it resolved the issue. I am able to login using LB endpoint. What @ckumar said makes sense but why isn't it causing any issue for my cluster? Is it because I am using just basic LB and not Reverse proxy?

@Tokolosk I would recommend that you provide java's cacerts as the keystore/truststore with the default password (changeit). This will work for most public certs. If you have a custom cert at the SFTP end you will need to import that cert and create your own keystore/truststore. I always try cacerts first.

I would need InvokeHTTP to read the attribute obtained from the previous request, done with the same processor. That was not a complaint, but desperation due to my incompetence. I guess that I am doing something wrong and that there will be a solution. Thank you again.

Could you probably give me an example of how to frame a Mongo query in NiFi ? My key to select the record is "my_id", which I get from an evaluate json path processor. The Columns that I want to update is a nested json key like so : ['a']['b']['exists_in_file']. The query that I now have in update Query Key is : {"$my_id":["a.b.exists_in_file":"True"]}. This errors our saying : BasicDBList cannot be cast to java.util.Map

Can you please provide any samples..

NiFi as a service alone can not autoscale irrespective of the type public/private cloud provided until it is customized and managed by different automation and scaling applications over the public cloud. But Cloudera offers NiFi as Data flow Expreinace in the public cloud which does support autoscaling Please check https://docs.cloudera.com/dataflow/cloud/release-notes/topics/cdf-whats-new.html for more info. Thank You.

@ravi_tadepally , Is your RabbitMQ configured to require TLS Mutual Authentication (or Client Authentication)? If so, you must also provide a keystore in the SSL Context in NiFi, besides the truststore. Cheers, André
