@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. Please help our community thrive.

Hi @Nicanor , Let's take a below example: Json Input: [
{
"cloud_base": [
"3500",
"15000"
],
"cloudType": [
"Stratocumulus",
"Altocumulus"
]
}
] Jolt Spec: [
{
"operation": "shift",
"spec": {
"*": {
"cloud_base": {
"*": {
"*": {
"@1": "cloud_base_&"
}
}
},
"cloudType": {
"*": {
"*": {
"@1": "cloudType_&"
}
}
}
}
}
}
] Output: {
"cloud_base_3500" : "3500",
"cloud_base_15000" : "15000",
"cloudType_Stratocumulus" : "Stratocumulus",
"cloudType_Altocumulus" : "Altocumulus"
} "Accept as Solution" if its work for you.

I got the Solution. Use UpdateAttribute processor and Expression Language. Here "SignedURL" is the attribute (containing complex Json) and from that I fetch particular Key value using Expression Language (JSONPATH)

you can use Grafana to monitor the server, they already have predefined dashboard template. More details https://pierrevillard.com/2017/05/16/monitoring-nifi-ambari-grafana/ https://grafana.com/grafana/dashboards/11387-nifi-monitoring/
