How to update Nifi on my HDP sandbox 2.4 and ambari to pick the latest version

[#1]

If the curl request errors out with the 500 error run the below command (from same README) and then re-try the original curl request

#if above errors out, run below first to fully stop the service
curl -u admin:$PASSWORD -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Stop $SERVICE via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}' http://$AMBARI_HOST:8080/api/v1/clusters/$CLUSTER/services/$SERVICE

I am facing the same issue. Did anyone have solution to resolve this issue!

I have Nifi old version service added in HDP 2.4. I followed the steps provided above

1. rm -rf /var/lib/ambari-server/resources/stacks/HDP/2.4/services/NIFI
2. sudo git clone https://github.com/abajwa-hw/ambari-nifi-service.git /var/lib/ambari-server/resources/stacks/HDP/2.4/services/NIFI
3. service ambari restart

After doing the steps, I am seeing all the services showing heart beat lost with question mark icon status!

I resolved this problem. I create a new VM hortonworks, and do not install nifi, after this, download the new version (https://www.apache.org/dyn/closer.lua?path=/nifi/1.0.0/nifi-1.0.0-bin.zip) and use sudo sh /opt/nifi-1.0.0/bin/nifi.sh start .The problem has been resolved and nifi update has concluded.
