Getting "Caused by: java.lang.IllegalStateException: HTTP Server cannot be loaded: No implementation of HttpServerFacade found on classpath." error


I am trying out the distributed random forest implementation of H2O using sparkling-water. But I am facing the following error when I run the spark-submit command.

Exception in thread "H2O Launcher thread" java.lang.ExceptionInInitializerError

I have tried out the solution mentioned at the location https://0xdata.atlassian.net/browse/TN-13

but for some reason it still isn't able to find the ai.h2o:h2o-jetty-8 on the classpath.


Solution

  • I resolved the issue by adding the following maven coordinates to the packages option in spark-submit

    --packages ai.h2o:h2o-jetty-8:3.24.0.3
