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.
I am getting below error in neo4j console.log after copying jar files from dependency folder of elasticsearch to plugin folder of neo4j

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.
I have a mapreduce job which takes an avro file as input. I export it along with all the required libraries (jar library files) into a jar file. I have 2 different clusters, one is HDInsight simulator and the other one in HDP sandbox. It works fine on the HDP sandbox but it gives me an error on the HDInsight simulator and cannot find AvroInputFormat class. I tried running the job with the -libjar option but it didn't help. Here is the error message:

This looks weired because it runs fine on one cluster! Does anyone know what can be the problem?
