I did end up getting a node started by running the following command: user@PTFAssaultMachine:~/apache-ignite-fabric-2.6.0-bin$ bin/ignite.sh /home/user/apache-ignite-fabric-2.6.0-bin/examples/config/example-ignite.xml
This started a node.. I then followed the instructions as provided in the Hello World example found here: https://apacheignite.readme.io/docs/genetic-algorithms <<-----by title Apache Zeppelin Integration and ran the following command in another terminal with a node,zeppelin already started in different terminal windows: user@PTFAssaultMachine:~/apache-ignite-fabric-2.6.0-bin/examples$ sudo mvn exec:java -Dexec.mainClass="org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample" This results in a strange situation where zeppelin works but doesn't show the tables as in the Hello World example(https://apacheignite.readme.io/docs/genetic-algorithms) we get a strange stack from the apache ignite node: user@PTFAssaultMachine:~/apache-ignite-fabric-2.6.0-bin$ bin/ignite.sh /home/user/apache-ignite-fabric-2.6.0-bin/examples/config/example-ignite.xml [01:40:26] __________ ________________ [01:40:26] / _/ ___/ |/ / _/_ __/ __/ [01:40:26] _/ // (7 7 // / / / / _/ [01:40:26] /___/\___/_/|_/___/ /_/ /___/ [01:40:26] [01:40:26] ver. 2.6.0#20180710-sha1:669feacc [01:40:26] 2018 Copyright(C) Apache Software Foundation [01:40:26] [01:40:26] Ignite documentation: http://ignite.apache.org [01:40:26] [01:40:26] Quiet mode.
