Hy! Thanks for the answer! My old nifi wasn't secured and didn't have users. In my new installation we have some users, in this error after inserting and configuring acess policies my error was resolved. Thank you!

Hi @dyadav1 Thanks for pointing out the direction for Kafka topic but I need little more help to determine the strategy, as I mentioned if every topic is putting 100 different types of command and I need to transform each type of command into new type (assuming Jolt transformation and have jolt spec for 100 different command types), how do I store those spec and make generalize flow so that new command types get added I just need to update Spec and flow didn;t require any changes. In more terms need to dynamically figure out which command type coming in the flow file and transform it based on spec, now I feel I need to use lookup and if I store all spec in database but then for each transformation I need to do database trip which I want to avoid.

Hi Steven, I used @bingo 's solution to get Nifi to find my JAVA_HOME. But you mention that Nifi does not need this to run. Do you know what is the impact for running nifi without it knowing where Java is installed?

thank you for the post but another question - according to the document - https://docs.cloudera.com/HDPDocuments/Ambari-2.7.0.0/administering-ambari/content/amb_changing_host_names.html The last stage is talking about – in case NameNode HA enabled , then need to run the following command on one of the name node hdfs zkfc -formatZK -force thank you for the post but since we have active name node and standby name node we assume that our namenode is HA enable example from our cluster but we want to understand what are the risks when doing the following cli on one of the namenode hdfs zkfc -formatZK -force is the below command is safety to run without risks ?

Policy is synced to all the nodes. You can check that in Ranger->Audit->Plugins. If not, then you should check if you have access policy for node identities,

You can try to use this command : http://<ambari-server>:8080/api/v1/stacks/{stackName}/versions/{stackVersion}/services To get help on API calls use this : http://<ambari-server>:8080/api-docs. You can try out api calls to understand what api returns.

Just to close this thread, we've detected that we miss a configuration inside the new configuration group (nifi.zookeeper.root.node). This parameter should be different in each configuration group in order to set a new path base where to save the new cluster configuration in Zookeeper (we didn't need to create the path, it was created as soon as we change the config). Now we have both groups of nifi instances up and running. Thanks for the help!

If ranger database is corrupted then only option is to drop and recreate it (if we dont have backup). Refer the below article for steps to create ranger DB: https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.1.5/installing-ranger/content/configuring_a_database_instance_for_ranger.html
