If you use timer scheduling it will still execute right away, so if you set 30 seconds it will run right away then wait 30 seconds before running again. Can you provide all of the configuration you entered for the processor? You would need to provide the "Maximum-Value Columns" in order for it to track where it left off and pick up there on next execution. ... View more

I suspect it is something more on the Hive side of things, which is out of my domain. Increasing the concurrent tasks on the PutHiveQL processor is the appropriate approach on the NiFi side, generally somewhere between 1-5 concurrent tasks is usually enough, but the concurrent tasks can only work as fast as whatever they are calling. If all 10 of your threads go to make a call to the Hive JDBC driver, and 2 of them are doing stuff, and 8 are blocking because of something in Hive, then there isn't much NiFi can do. ... View more

If you added the correct dependencies in your processor's pom file then they should be getting included in the generated NAR, as Andrew mentioned above. Please verify you have the correct project structure described here: https://cwiki.apache.org/confluence/display/NIFI/Maven+Projects+for+Extensions#MavenProjectsforExtensions-ProcessorProjects There should be a Maven project with two sub-modules, one for the processors JAR where you would put your dependencies in the pom file, and another for building the NAR. ...

It is a resource identifier for a policy that should be auto-generated for each node that you put in "Node Identities". Normally you would go to the UI and go to the global policies from the top-right menu, but since you can't get into the UI you can check the users.xml and authorizations.xml. There should be a user for each cluster node in users.xml, and there should be a policy in authorizations.xml for /proxy that all the cluster node users belong to. ... View more

Was the DN in the access denied message one of the DNs in the Node Identities? Every node in the cluster needs to have READ access on /proxy which is defined through the global policies in the top right menu. The Node Identities should get this policy automatically, but you can double check if your node is in the list for /proxy, and if not add it. ... View more
