Dear Apache Ignite Community,
I was trying to run the Hello World example in Apache ignite Genetic Algorithm codes and I ran into the following error or code stack which seems to be preventing me from seeing the result in zeppelin after following the instructions here:https://apacheignite.readme.io/docs/genetic-algorithms In the section titled Apache Zeppelin Integration,here is the stack from terminal: [2018-11-29 21:00:10,659][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][root] Chromosome: Chromosome [fitnessScore=11.0, id=302, genes=[8, 5, 12, 12, 15, 27, 23, 15, 18, 12, 4]] [2018-11-29 21:00:10,659][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][root] HELLO WORLD [2018-11-29 21:00:10,659][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][root] Avg Chromosome Fitness: 5.198 [2018-11-29 21:00:10,659][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][root] ########################################################################################## [2018-11-29 21:00:10,672][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][GridTcpRestProtocol] Command protocol successfully stopped: TCP binary [2018-11-29 21:00:10,702][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][GridCacheProcessor] Stopped cache [cacheName=ignite-sys-cache] [2018-11-29 21:00:10,702][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][GridCacheProcessor] Stopped cache [cacheName=geneCache] [2018-11-29 21:00:10,705][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][GridCacheProcessor] Stopped cache [cacheName=populationCache] [2018-11-29 21:00:10,742][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][GridDeploymentLocalStore] Removed undeployed class: GridDeployment [ts=1543543165925, depMode=SHARED, clsLdr=java.net.URLClassLoader@e1f29d3, clsLdrId=2d487526761-9633e22a-ae9a-4b73-85d5-b8263ffad2e0, userVer=0, loc=true, sampleClsName=org.apache.ignite.internal.processors.service.GridServiceProcessor$ServiceDeploymentPredicate, pendingUndeploy=false, undeployed=true, usage=0] [2018-11-29 21:00:10,754][INFO ][org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample.main()][IgniteKernal] >>> +---------------------------------------------------------------------------------+ >>> Ignite ver. 2.6.0#20180710-sha1:669feacc5d3a4e60efcdd300dc8de99780f38eed >>> stopped OK >>> +---------------------------------------------------------------------------------+ >>> Grid uptime: 00:00:44.882 Nov 29, 2018 9:00:10 PM java.util.logging.LogManager$RootLogger log SEVERE: jvm-pause-detector-worker has been interrupted java.lang.InterruptedException: sleep interrupted at java.lang.Thread.sleep(Native Method) at org.apache.ignite.internal.LongJVMPauseDetector$1.run(LongJVMPauseDetector.java:90) [WARNING] thread Thread[FileWatchdog,5,org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample] was interrupted but is still alive after waiting at least 14999msecs [WARNING] thread Thread[FileWatchdog,5,org.apache.ignite.examples.ml.genetic.helloworld.HelloWorldGAExample] will linger despite being asked to die via interruption [WARNING] NOTE: 1 thread(s) did not finish despite being asked to via interruption.
