I think the easiest way is to create a new cloud-xyz subproject in your fork. The simplest implementation is our cloud-mock implementation which is used for testing, but implements all of the requirements without 3rd parties. ... View more

I think you have to check the log on the zookeeper side, my advice is to increase the value of "nifi.zookeeper.connect.timeout" and "nifi.zookeeper.session.timeout" settings. Also check your network connection between the Zookeeper servers and Nifi servers, Network latency can cause the issue. ... View more

@Benjamin Hopp What reason if NiFi giving in the nifi-app.log for the node disconnections? Rather then restarting the node that disconnects, did you try just clicking the reconnect icon in the cluster UI? Verify that your nodes do not have trouble communicating with each other. Makes there are no firewalls between the nodes affecting communications to the HTTP/HTTPS ports: nifi.web.http.host=nifi-ambari-08.openstacklocal nifi.web.http.port=8090 nifi.web.https.host=nifi-ambari-08.openstacklocal nifi.web.https.port=9091 or node communication port: nifi.cluster.node.address=nifi-ambari-08.openstacklocal nifi.cluster.node.protocol.port=9088 Make sure Both yo r nodes are properly configured to talk to ZK and neither has issues communicating with them: nifi.zookeeper.connect.string=nifi-ambari-09.openstacklocal:2181,nifi-ambari-07.openstacklocal:2181,nifi-ambari-08.openstacklocal:2181 nifi.zookeeper.connect.timeout=3 secs nifi.zookeeper.root.node=/nifi nifi.zookeeper.session.timeout=3 sec All of the above setting are in the nifi.properties file.

I have installed HDP 2.5 and Atlas 0.7.0.2.5 and I don't need HBase to use Atlas. Currently I'm using Solr (Ambari Infra) as the index engine and Berkeleyje as the storage engine. The real dependency between Atlas and HBase is the AuditRepository, by default use HBase. Is not easy change it, but investigating the source code I found a special property atlas.EntityAuditRepository.impl that you have to set with the value org.apache.atlas.repository.audit.InMemoryEntityAuditRepository (is case sensitive, so copy&paste exactly the name of the property and the value). @Chad Woodhedad, add the above property as the screenshot shows, restart Atlas services and you will have it, Atlas without HBase 🙂 And now some details about how I found that property: In this link from GitHub you can see why Atlas by default needs HBase. And in this link from GitHub you can find the available values that you can use for configure the audit. Don't worry about the rest of the properties related with HBase. Atlas will use the value of atlas.graph.storage.hbase.table to create the table in the storage backend that you choose (Berkeleyje or Cassandra). With these properties my Atlas services work very well. I hope this information is helpful and work for you to avoid install HBase in your clusters. ... View more
