Hi All, At the bottom you can find my question. Note, I am positive this is more a network issue, but I cannot seem to figure out the solution. I tried posting this to the Neo4j Google+ board <https://groups.google.com/forum/#!forum/neo4j> , and as a relevant NiFi-Neo4j Github issue <https://github.com/jonathantelfer/nifi-neo4j> (I know this is not an official NiFi-supported processor, so you can handle this thread how you wish); however, no luck. First, here is the structure of my architecture:
Windows 8 host machine with Windows Hyper-V Manager. Hyper-V Manager has 6 RHEL nodes running a Hadoop cluster--Hortonworks. I have NiFi 1.0.0.2.0.1.0-12 (no SSL enabled) on HDF (Hortonworks Data Flow). On the Windows host machine, I have Neo4j Enterprise (trial) edition 3.1.3. Windows/Neo4j configuration: - I found that my windows IP address i (windows.ip.address) - I started Neo4j EE and confirmed that the browser client works. - I went into the neo4j.conf file and enabled the property "dbms.bolt.connector.listen_address=0.0.0.0:7687, which allows Neo4j to listen on all networks - I also went into the Neo4j browser, went down to the settings tab, and configured the database URI to be bolt://(windows.ip.address):7687 (default is bolt://localhost:7687) - Additionally I did a netstat -a to see that the TCP connection is active and I have a service listening to 0.0.0.0:7687 and [::]:7687 Linux/NiFi configuration: - According to the NiFi-Neo4j Github I linked above, I created a Neo4jBoltSessionPool Controller Service and specified the Bolt DB Connection URL to be a variety of things (0.0.0.0:7687, localhost:7687, (windows.ip.address):7687, (foreign.ip.address):7687, etc) - Created a PutCypher processor and put in a simple LOAD CSV WITH HEADERS FROM ${file_path} cypher query When I pass in a FlowFile (I have confirmed that the file path is saved as the file_path FlowFile attribute) and run the PutCypher processor, I get an error saying that the neo4j driver was "unable to connect to (ip.address):7687, ensure the database is running and that there is a working network connection to it" Is my configuration wrong or could it be that the Windows firewall is preventing communication to the bolt address:port? -- View this message in context: http://apache-nifi-developer-list.39713.n7.nabble.com/NiFi-Neo4j-Issues-tp15654.html Sent from the Apache NiFi Developer List mailing list archive at Nabble.com.
