Hi @Chad Woodhead, This property needs to be set if and only if you are doing S2S using RAW protocol. Any reason not to use HTTP protocol for S2S? This way, you don't have anything to set and it'll work OOTB with default configuration. If, however, you want to use RAW and you are configuring NiFi using Ambari, you don't need to use config groups, you can set the property to: {{nifi_node_host}} It's a placeholder that contains the FQDN of each node. Note that this property already has a default value generated if you let it blank (see the description of this property in Ambari). Unless you have a specific network configuration, the only property you would need to specify is nifi.remote.input.socket.port to define the port that will be used for RAW S2S. Hope this helps.

Hi @Amira khalifa, Why don't you want to define the schema or your target tables in the schema registry? You can use InferAvroSchema to help you initializing the schema, then you can adapt it and copy/paste it into the schema registry of your choice. Using InferAvroSchema for every single flow file you'll ingest can be costly in terms of performance and it's only inferring the schema on a subset of data: as you can see, the schema might not be completely correct to take into account all the possibilities. What you could do, even though it's not what I'd recommend as a long term solution, is to use expression language to update the avro schema generated as an attribute of your flow files. Hope this helps.

Hi @Manikandan Jeyabal, This is not possible at the moment. The number of threads used at one point in time can be set at NiFi level. There is no way to fix the size of the threads pool per Process Group. It could be an interesting feature, feel free to raise a JIRA on https://issues.apache.org/jira/projects/NIFI Hope this helps.

Hi, What are the RUNNING jobs that stop making progress? In particular are these jobs oozie-launcher jobs? You can check that by looking at the name of the jobs in the Scheduler view of the RM UI. Oozie has a non-intuitive way of launching jobs due to legacy behaviors from Hadoop 1 (note that this will be fixed with Oozie 5.x). In short, an Oozie action will launch an oozie-launcher job (1 AM container + 1 mapper) that will be responsible for actually launching the job that you defined in your Oozie action. In the end, your Oozie action will actually require two jobs from YARN point of view. When running multiple workflows at the same time, you could end with a lot of oozie-launcher jobs filling up the queue capacity and preventing the actual jobs to be launched (they will remain in ACCEPTED state). A common practice is to have a dedicated queue for oozie-launcher jobs created by Oozies workflows. This way you prevent this kind of deadlock situation. IIRC, you can set the queue for oozie-launcher jobs using oozie.launcher.mapred.job.queue.name. Hope this helps.

Hi Jay, You need to provide a file such as https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/test/resources/TestExtractGrok/patterns You could also use the ConvertRecord processor with a GrokReader. In this case there is already a default pattern file pre-loaded with the reader. Hope this helps, Pierre

In case someone faces the same issue: in my case, I solved it by ensuring that 'atlas' user is known in Ranger.

Hi @msumbul, The ConvertJsonToSQL processor has been developed to work with the SQL processors. The Hive processor is expecting a different naming convention on the attributes, instead of: sql.args.N.type/value it is expecting: hiveql.args.N.type/value The syntax between SQL and HQL are close enough and the generated query is also valid for Hive but the attributes need to be renamed. What you can do is to use an UpdateAttribute processor to have the expected attributes before using the PutHiveQL processor. Hope this helps.

@Onkar Pathak You can use a GET for this.
