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.

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.
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

I have a big problem. When I'm building my Project, I get this Error:
com.eurofunk.RaceComApplicationTests > contextLoads FAILED
java.lang.IllegalStateException
Caused by: org.springframework.beans.factory.BeanCreationException
Caused by: org.springframework.beans.BeanInstantiationException
Caused by: java.lang.UnsatisfiedLinkError
Could you please help me?
A UnsatisfiedLinkError is thrown
if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.
So this does not look like a spring related problem.
It looks more like a problem with the JRE or a bean tries to find a native library which does not exist.

Your problem could be because Neo4j and ElasticSearch using different version of Lucene.
In JVM you can't have one jar with two different versions.

How do I run a Play Framework 2.0 application as a Windows service?
And i failed at step 5.
At first the service showed an error regarding the
play.core.server.NettyServer
part of the script.
I changed it to
play.core.server.ProdServerStart
But now I get an error running the start.bat saying
C:\GCS>java -cp "C:\GCS\lib\*" play.core.server.ProdServerStart
Oops, cannot start the server.

I've looked for a solution for this everywhere, but couldn't find any.
I guess something else has changed in the way the dist is built since the original answer was given.
Anyone knows what could be the issue?
You need the config. on the classpath as well ie. depending on where your conf is, try something like the following (untested):
java -cp ".conf;.;lib/*" play.core.server.ProdServerStart
I am currently trying to install hadoop 2.3.0 on my cluster. However, when I run command "bin/hdfs namenode -format", I got this error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/security/authorize/RefreshAuthorizationPolicyProtocol
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.security.authorize.RefreshAuthorizationPolicyProtocol
Any ideas how to solve it?
There isn't much information in the question, but this error will occur if the environment variable HADOOP_COMMON_HOME is not correctly set to $HADOOP_HOME (the top level where HADOOP is installed).
