I am new to drools, testing it out to create kie session and while I tried to do that, I get this error. Followed this tutorial to do it

Can anyone help with why this could be happening? I added the main class, the pom file and my error what I get. I am not able to figure out where the error lies. I did a step by step implementation of the link above.
Please add the below dependency into your POM.xml
<dependency>

You should remove this dependency:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>5.1.6.RELEASE</version>
</dependency>
It is conflicting with the dependencies provided by spring-boot-starter-security. Additionally, Spring Boot 3 uses Spring Security 6 and the jakarta namespace instead of javax.
I have an example spring boot project which uses mongo db for persisting objects. I would like to test it with an embedded mongo db but I get an error which is very similar to this question (see comments of the accepted answer): For some reason IFeatureAwareVersion from flapdoodle cannot be found.

The Spring boot start parent 2.0.0.RELEASE manages the version of flapdoodle which is 2.0.3 and I see the class IFeatureAwareVersion in the de.flatpdoodle.embed.mongo-2.0.3.jar.
When I look at the dependancy hierarchy I see
embedmongo-spring: 1.3.1 [test]
de.flatpdoodle.embed.mongo: 2.0.3 (managed from 1.46.4) (ommitted for conflict with 2.0.3) [test]
de.flatpdoodle.embed.process: 1.40.1 (ommitted for conflict with 2.0.2) [test]
Here is the test
#RunWith(SpringRunner.class)
#SpringBootTest(classes=MongoConfig.class)
#TestPropertySource(locations = "classpath:application-test.properties")
public class Test_TimezoneDao {
private static final Logger LOG = LoggerFactory.getLogger(Test_TimezoneDao.class);
//#Autowired private TimezoneDao dao;
#Autowired private CounterService counterService;
#Autowired
private MongoTemplate mongoTemplate;
#Test
public void test()
{
TimeZone tz = new TimeZone();
tz.setId(counterService.getNextSequence());
tz.setOffset(9);
tz.setTz("Asia/Singapore");
TimeZone tz2 = new TimeZone();
tz2.setId(counterService.getNextSequence());
tz2.setOffset(11);
tz2.setTz("Australia/Sydney");
mongoTemplate.save(tz);
List<TimeZone> tzs = mongoTemplate.findAll(TimeZone.class, "timezones");
for(TimeZone t : tzs)
{
LOG.info(t.toString());
}
}
}
and here is the test config
#SpringBootConfiguration
#Profile("test")
#ComponentScan(basePackages= {"com.example.demomongodb"})
#EnableJpaRepositories(basePackages= {"com.example.demomongodb"})
#EnableMongoRepositories(basePackages= {"com.example.demomongodb"})
#EntityScan(basePackages= {"com.example.demomongodb"})
#EnableAutoConfiguration
public class MongoConfig
{
public MongoConfig()
{
System.out.println("============= LOADING MONGO CONFIG ===============");
}
#Bean
public MongoTemplate mongoTemplate() throws IOException {
EmbeddedMongoFactoryBean mongo = new EmbeddedMongoFactoryBean();
mongo.setBindIp("localhost");
MongoClient mongoClient = mongo.getObject();
MongoTemplate mongoTemplate = new MongoTemplate(mongoClient, "test_or_whatever_you_want_to_call_this_db");
return mongoTemplate;
}
}
Thanks for the help
embedmongo-spring is kinda deprecated, it is embed mongo is now integrated directly into spring boot not via a third party dependency.
Just remove this dependency and you should be done.
You can also take a look at this issue, which explains the situation a bit further
https://github.com/flapdoodle-oss/de.flapdoodle.embed.mongo/issues/260
de.flapdoodle.embed dependency will be added through cz.jirutka.spring.
[INFO] +- cz.jirutka.spring:embedmongo-spring:jar:1.3.1:compile
[INFO] | +- de.flapdoodle.embed:de.flapdoodle.embed.process:jar:1.40.1:compile

[INFO] | \- org.mongodb:mongo-java-driver:jar:3.11.2:compile
[INFO] +- de.flapdoodle.embed:de.flapdoodle.embed.mongo:jar:2.2.0:test
This issue is fixed by excluding the de.flapdoodle.embed.process from cz.jirutka.spring dependency.

Looks like you got two incompatible Versions of log4j referenced that don't play well together. Use the dependency-tree function of maven to identify where this different versions come from:
mvn dependency:tree -Dverbose
Then exclude the wrong one by using the exclude functionality of maven:
<dependency>
<groupId>group-of-responsible-jar</groupId>
<artifactId>artifactId-of-responsible-jar</artifactId>
<version>...</version>
<exclusions>
<exclusion>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
</exclusion>
</exclusions>
</dependecy>
I have the below spark word count program :

import scala.Tuple2;
public class SparkWordCount {
public static void main(String[] args) {
SparkConf conf = new SparkConf().setAppName("wordcountspark").setMaster("local").setSparkHome("/Users/hadoop/spark-1.4.0-bin-hadoop1");
JavaSparkContext sc = new JavaSparkContext(conf);
//SparkConf conf = new SparkConf();
//JavaSparkContext sc = new JavaSparkContext("hdfs", "Simple App","/Users/hadoop/spark-1.4.0-bin-hadoop1", new String[]{"target/simple-project-1.0.jar"});
JavaRDD<String> textFile = sc.textFile("hdfs://localhost:54310/data/wordcount");
JavaRDD<String> words = textFile.flatMap(new FlatMapFunction<String, String>() {
public Iterable<String> call(String s) { return Arrays.asList(s.split(" ")); }
});
JavaPairRDD<String, Integer> pairs = words.mapToPair(new PairFunction<String, String, Integer>() {
public Tuple2<String, Integer> call(String s) { return new Tuple2<String, Integer>(s, 1); }
});
JavaPairRDD<String, Integer> counts = pairs.reduceByKey(new Function2<Integer, Integer, Integer>() {
public Integer call(Integer a, Integer b) { return a + b; }
});
counts.saveAsTextFile("hdfs://localhost:54310/data/output/spark/outfile");
}
}
I get the Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.fs.CanSetDropBehind exception when I run the code from ecllipse however if I export as runnable jar and run from the terminal as below it works :
bin/spark-submit --class com.sample.spark.SparkWordCount --master local /Users/hadoop/spark-1.4.0-bin-hadoop1/finalJars/SparkJar-v2.jar

When you run in eclipse, the referenced jars are the only source for your program to run. So the jar hadoop-core(thats where CanSetDropBehind is present), is not added properly in your eclipse from local repository for some reasons. You need to identify this if it is a proxy issue, or any other with pom.
When you run the jar from terminal, the reason for running can be, due to the presence of jar in the classpath referenced. Also while running from terminal, you could also choose to have those jars as fat jar(to include hadoop-core) in your jar. I hope you are not using this option while creating your jar. Then the reference would be picked from inside your jar, without depending on the class path.
Verify each step, and it will help you identify the cause. Happy coding
Found that this was caused because the hadoop-common jar for the version 0.23.11 did not have the class,changed the version to 2.7.0 and also added below dependency :
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-mapreduce-client-core</artifactId>
<version>2.7.0</version>
</dependency>
Got rid of the error then but still seeing the below error :
Exception in thread "main" java.io.EOFException: End of File Exception between local host is: "mbr-xxxx.local/127.0.0.1"; destination host is: "localhost":54310; : java.io.EOFException; For more details see: http://wiki.apache.org/hadoop/EOFException
