I per MS SQL docs I found this example String connectionUrl = "jdbc:sqlserver://localhost:1433;" + "databaseName=AdventureWorks;integratedSecurity=true;" + "encrypt=true; trustServerCertificate=false;" + "trustStore=storeName;trustStorePassword=storePassword"; Can you please check ? also the URL which you have used works outside of nifi ?

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.

How you are passing SSL details in DBCPConnectionPool used by ConvertJSONToSQL? in configured JDBC URL?

Ok, so you got the copy file in NiFi using List/FetchFile then you changed the new directory location where it has to be written using UpdateAttribute then you have used DuplicateFlowFile to create duplicates, till now what is happening since ListFile is running on Primary node (And it should be running on Primary ) rest all downstream flow will be processed/computed on Primary that why you see DuplicateFlowFile creating duplicated on node which is Primary in NiFi Cluster. I do not see any issue here. If you wish to have flow files on All NiFi nodes redistributed after DuplicateFlowFile then you need to set Load Balancing at queue connection on the connection "Round Robin " between DuplicateFlowFile & PutFile, by doing this duplicates flow files will be distributed among nifi nods in round-robin manner one by one and will be written by PutFile back on each nifi nodes where files got distributed after DuplicateFlowFile. Now one question you mention 7 HDFS data nodes, does that means you have NiFi service running as well on the same 7 data nodes ? and having 7 node nifi cluster? in that case, only all 7 nodes will receive each file copy. I see

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.

Sorry some confusion here ,so you saying The file is placed by a third party onto an SFTP location on one node? so the file is on SFTP server at this stage but only on node ? and then you fetch the file into NiFi using List/FetchSFTP processor running on Primary node only ? then ? what is the end goal "we want the file to be available on all nodes so that the receiving team can access it". What do you mean by All nodes is these NiFi nodes or SFTP nodes ?

Why do you want to do that ? NiFi cluster is not like HDFS where data will be replicated across nodes NiFi is not a storage system. What NiFi provides as , let's say you have 3 node cluster and you receive 100 files on one node assuming Processor which one is receiving file running on Primary node,now you want to processor these all 100 files in distributed manner using all 3 nodes , then you need to use Load Balancing at queue connection to distribute 100 file on 3 nodes , 33/33/34 files on each node then rest further downstream processing will be done on all 3 nodes. Example flow design flow be, ListSFTP (Primary)-->Connection set to LB at queue tion --> FetchSFTP, in this use case ListSFTP will list the file details on Primary node then FetchSFTP will fetch the file from SFTP server on All 3 nodes in a distributed manner.

SSLHandshakeException: PKIX path building failed, which means one or more certificated chain is missing thus SSL handshake is failing, Can you check and confirm if NiFi and NiFi Registry are both signed by same certificate signing Authority ? if not then please make sure you have imported/exchanged complete trusted chain in truststore file used by NiFi and NiFi Registry vice versa
