@Ytch  All components on the NiFi canvas are executed as the NiFi service user and not as the user currently authenticated into the NiFi service.   So what you should do is from each host in your NiFi cluster (do on every host since any one of the hosts can be elected as the primary node at any given time), open a command prompt window/console window, become the user that owns the NiFi process, and manually ssh/sftp to the target SFTP server.  You will likely be prompted to add the target SFTP server to your known_hosts file for the NiFi service user.  NiFi SFTP processor has no way of doing this interactive step.  After successfully adding the SFTP to the known_hosts file for the NiFi service user, go back and try to start the GetSFTP or ListSFTP processors again to see if your issue is resolved. If not, please share your GetSFTP and ListSFTP processor component configurations. Also check the nifi-app.log for any exceptions or log output related to these processors. If no log output, you could also try enabling debug in the NiFi logback.xml for these processor classes to see what additional log output may be produced that could be useful here. classes for these processors are: org.apache.nifi.processors.standard.GetSFTP org.apache.nifi.processors.standard.ListSFTP new log lines would look like this that you would add to logback.xml: <logger name="org.apache.nifi.processors.standard.GetSFTP" level="DEBUG"/> <logger name="org.apache.nifi.processors.standard.ListSFTP" level="DEBUG"/> Simply add them in logback.xml where you see similar lines already.

Hi @Ytch , The way I was able to get to work is through the following instruction: 1- After you have download the jdbc drive from here: https://learn.microsoft.com/en-us/sql/connect/jdbc/download-microsoft-jdbc-driver-for-sql-server?view=sql-server-ver15 you should be able to find the following dll "mssql-jdbc_auth-8.2.2.x64.dll" under the path: ..\sqljdbc_8.2\enu\auth\x64 2- Copy the dll and place under the JAVA Home path bin folder: .. \Java\jdk-21\bin 3- Adjust the DB Connection URL in the DBCPconnectionpool  controller service by adding and setting "integrated security"  flag to true: jdbc:sqlserver://{SQL SEVER NAME};databaseName={DB NAme};integratedSecurity=true; 4- Restart Nifi If that helps please accept solution.

hi @Ytch , To use the PutDatabaseRecord you need to have the column names defined in whatever input format you have (CSV, Json....etc.) and the column name should match what is in the DB table ( see also the "Translate Field Option" if not exactly the same). If you know the column order in the CSV file you can add a header using the ReplaceText processor as described here: https://community.cloudera.com/t5/Support-Questions/How-to-add-customer-headers-to-csv-file-in-NIFI/m-p/285457   If you find this is helpful please accept solution.
