Exception in Connecting Dataproc Hive Server using Java and Spark Eclipse

I am trying to access the Hive server present in GCP - Dataproc from my local machine(eclipse) using java and spark. But I am getting the below error while starting the application. I tried to find the problem but unable to solve it.
Exception in thread "main" java.lang.IllegalArgumentException: Unable to instantiate SparkSession with Hive support because Hive classes are not found.

</dependency>
According to the Maven doc:
compile: This is the default scope, used if none is specified. Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.
provided: This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. A dependency with this scope is added to the classpath used for compilation and test, but not the runtime classpath. It is not transitive.
You might want to change it to compile or remove the line. Or download the jar and add it to the classpath.
Also see this doc on how to create a Spark application uber jar which includes its dependencies.

Spring Boot Embedded Keycloak server throwing NoSuchMethodError

I've been playing around with spring boot and stumbled onto a guide about embedding Keycloak into a Spring Application, I thought this would a fun little project so I have been following This guide.
I have implemented everything and the project is building, but crashing at start. This is the error:
java.lang.NoSuchMethodError: 'org.infinispan.configuration.global.GlobalJmxStatisticsConfigurationBuilder org.infinispan.configuration.global.GlobalConfigurationBuilder.globalJmxStatistics()'
I've searched around for a bit and haven't had much luck. I've tried messing around with the dependencies to see if I am missing something, I have also verified that I can import org.infinispan.configuration.global.GlobalConfigurationBuilder; which is available, so could be version conflicts? Any help would be appreciated.

„…so could be version conflicts?…“
That is it, essentially. It all starts with…
…
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.4.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
…
You upgrading from Baeldung's original 2.2.6.RELEASE of Spring Boot to 2.3.4.RELEASE, caused a whole cascading domino affect of incompatible dependencies.
Unless you desperately need to be on 2.3.4, my advice is to just roll back to 2.2.6.RELEASE. Or else you'll need a machete as long as your arm to hack your way through the tangled morass of incompatible dependencies that results from that upgrade.
I've pushed this working demo to confirm that 2.2.6.RELEASE at least works with JDK 15.

I have the same issue.
The maximum versions i have updated in my pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.12.RELEASE</version>
<relativePath />
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>15</java.version>
<keycloak.version>11.0.3</keycloak.version>
<!-- these should be updated together with Keycloak -->
<!-- check keycloak-dependencies-server-all effective pom -->
<infinispan.version>10.1.8.Final</infinispan.version>
<resteasy.version>3.12.1.Final</resteasy.version>
</properties>
I have tried to update the keycloak to any versions more than 11.0.4 version and the spring boot more than 2.3.12.RELEASE but it's impossible - incompatible versions. Maybe who knowns how to update?

Getting Error java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config

I am developing a spring boot project. The code works perfectly fine on localhost in intelliJ.
The war file was created using command
mvn clean install
But when I run it on centos server with command
java -jar app.war
On running above command the deploy is successfully started at port 8080
But the problem occurs when any page containing jstl jsp is access. It displays 404 error
following error is visible on log. This code was working perfectly fine few days ago but now I cant get what changed except I made few code changes and deployed the new war file. I haven't changed anything in pom.xml.

I tried both the ways w/ and w/o provided

I think the problem here is that you are using the "provided" scope for your servlet. The provided scope means it will be used for build and testing but not for runtime, as it will be provided by the runtime environment (container, specific server..). You should remove the scope if you want to run it with cli.

It is not possible to run a war file outside of a container.Remove war from POM this will set packaging to default(jar).
Then use below command in CentOS to run the project.
java -jar app.jar
The other solution is to install a container in CentOS and then deploy the War to it.

How resolve problem with tomcat ? Spring-Boot " Failed to scan"

this is my first spring-boot project and i have problem with tomcat. Server don't wan't to start. Glass fish is not used in the project, the more I am surprised by this message. The project was created in Maven.
I have sitting about this problem many hours and I can't find the problem. Enybody can help me ?

i have also faced this problem so we can't use concurrently spring-boot-starter-web and spring-boot-starter-jersey because glassfish is part of jersey so just remove any one dependency from both of them in my case i removed starter-jersey
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jersey</artifactId>
</dependency>
finally problem has been gone please try it

You should add the packaging to war at the pom.xml:
<packaging>war</packaging>

It seems something wrong with your dependencies : can you check this typo
tomcat-embed-jasper dependency
providet
Other question why you have two dependencies if you are using tomcat one will be fine.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>providet</scope>
</dependency>
check that example pom
spring boot web dependency is enough it already includes tomcat. You don't need to explicitly define tomcat dependency
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

If it is a new project i would try to run a standard project generated on: https://start.spring.io/. This way you can be sure the project should be runnable and any failure is to blame on anything other than the project or IDE. If that does not run i would reinstall Tomcat.

How to remove duplicates in my WEB-INF/lib jar files?

I know there seems to be a lot of discussion on StackOverflow about the error I am getting, but I don't see exactly the same situation and I'd like to better understand the issue I am having.
I am getting the following failed to start error "Caused by: org.apache.catalina.LifecycleException: A child container failed during start"
After doing some research it seems like this is a WEB-INF/lib and/or a pom.xml dependency issue. It looks like people have been able to solve their issues by removing a variety of jar files or updating their pom file/removing a variety of certain dependencies.
When I look at my WEB-INF/lib jar files, it seems that mine are duplicating... Does any one know why I am getting double/2 versions of the same jar files, and could they tell me which dependency they are coming from in my pom.xml file? I think my project wont start on Tomcat & is getting this issue due to the duplicates, as things are already running once when it tries to start the other duplicate jar files.
