@toninghaywi Looks like you are trying to enable TLS for NiFi UI. Please make sure all the properties are correctly configured and the service should start fine. If you are not trying to enable the TLS for NiFi and still you are seeing this issue then you can try to remove all the TLS related properties from CM > NiFi > Configs.

@mt13 Looking at this It seems like the property nifi.cluster.protocol.heartbeat.missable.max made configurable on NiFi 1.12, before this it is using the default value of 8. Which is the reason you are not able to get the expected timeframe results. But instead of looking to tune the timeouts to higher values, you should look to tune the dataflow designs. The lack of heartbeat is mostly occurring due to high resource utilization either memory or CPU or network. The choice of processors and incoming data has to be analyzed for a more stable cluster. In NiFi-1.12 a new feature was added to review the node status history from NIFi UI > Global Menu > Node Status History. It shows the resources utilization in graphical form for each node which would be a great indicator to analyze the load, incoming traffic, heap utilization, etc.

@Chakkara The behavior you are seeing is looking similar to NIFI-8470 . A quick fix for the issue on NiFi-1.13 is to alter the table column to varchar. The behavior introduced by NIFI-8223 . This is fixed in NiFi 1.14 so an upgrade can be done if table schema alter is not an option.

@Masi Load Balancing related issues are fixed in NiFi 1.10, so you should not be hitting any known issue in this version. On LB queue how many flowfiles you pass at any given point? How many nodes you have? If you are passing one flowfile and till the time it processed/passed to next processor there is no flowfile in queue then it is possible that NiFi not load balancing the flowfiles at all as it doesn’t have enough flowfiles. Also on load balancing queue you should have an icon representing LB queue, do you see that icon color changing from green to grey? If icon is green means it is load balancing the flowfiles and if grey then it finished the balancing.

@Delio It would be bit complicated flow design as direct support for delete events is not available for GetHDFSEvents processor yet. But you can refer this solution, which can help you to move further. If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.

@Law serveraddress is hostname of host where nifi service is installed. E.g you have installed it on samplehost.com then it would be "http://samplehost.com:8080/nifi" .If you enable SSL for nifi later then the URL will change to "https://samplehost.com:<secure_port>/nifi". Also you should check that host and port are reachable from your browser to access NiFi UI.

@dzbeda You can use one of below approach. 1. Install minifi on windows machine and send logs from minifi to NiFi [Push] 2. You can use ConsumeWindowsEventLog to get event logs in NiFi [Pull]

@Delio What do you mean by "But what about file delete?" Do you want to delete the data at source HDFS as soon as you fetch it in NiFi?

@sarithe It is expected behaviour as Ranger has to pull resources from NiFi and as NiFi is secured it will look for authentication token from Ranger but as Ranger is un-secure it can not present the token and get 403 as response. You should enable SSL [or kerberise the cluster] for Ranger so Ranger can authenticate using SSL [or tgt]certificate. Meanwhile you can use https://community.cloudera.com/t5/Community-Articles/NiFi-Ranger-based-policy-descriptions/ta-p/246586 as reference to setup policies manually. -Akash
