I want to create a website, and part of the website I will implemented with(Hadoop mapreduce). I start using the Eclipse with maven plugin, on my operating system (Mac OS).
I start coding with apache maven for my code. "I still not implement the website".
My question does the maven run with cluster of machines or not?
any advice of how can I create a website with part run in mapreduce??
Please help
Thanks all
Apahe Maven is not "something, that runs our code". It's actually a build tool: Apache Maven is a software project management and comprehension tool. (https://maven.apache.org/). You can manage dependencies, build, deploy and do other related stuff.
If you want some interface to your cluster, I recommend to look at zeppelin (https://zeppelin.apache.org/).
It's an interpreter for a bunch of stuff and it can be easily deployed to your server (I did it by building sources from https://github.com/apache/zeppelin and running it). Zeppelin's spark interpreter can be run in yarn-client mode, which just submits your code to cluster (yarn hadoop cluster in my case) and runs it.
Seems pretty similar to your description.
The answer to your question: maven had nothing to do with "running on cluster".

So I am relatively new to Docker and I was wondering if there is a way with either docker-compose or cloud-cli to create a Java environment with different plugins and other software needed for an application?
For example, I would like to start with configuring Eclipse, Java, Tomcat, and Maven together as one environment natively. And if so could you explain and maybe show an example of how to do this? I am on a Windows 10 machine.
Thanks in advance.
You can totally do that using Docker-compose for java, tomcat and maven.
For eclipse it will be kinda problematic since it's a graphical application, but you still can do it using volumes.
You could also consider using Vagrant if it's for a development environment.
I'm currently experimenting with the idea of having a full cloud development environment. I decided to go with Cloud9 IDE and deploy my app on Heroku while using GitHub to store my code. As Java is my most comfortable language, I'm adopting it for my app.
Now the Heroku tutorials use Maven for Java packaging. Is there any way I can replicate this in Cloud9, or can I skip the Maven altogether? Or must I manually put in all the pom files myself?
Note: I do intend to install Toolbelt on my local machine, but there will be times when I want to do coding when I'm not at home and don't have access to the local server. I'm more interested in knowing if it is possible to not have any dependence on a local machine at all.
Not at the moment as Cloud9 lacks build tools for Java. A thing called 'private RunVMs' will be launched in the next couple of weeks that allow you to install a Java build environment from within Cloud9; then deploying to Heroku would be possible for Java apps as well. Keep an eye on the blog for updates.
edit Cloud9 now has private VMs. It should be possible to install a java runtime in Cloud9 if you are on a premium plan now.
What are the limitations of TFS in heterogeneous development environments?
I have little expirience with Jenkins and like the possibility to run all those different kinds of jobs, like Ant, Maven, CMD, Powershell, ...
Is it possible to check coding conventions when building a java project with team foundation server?
I do not know how java builds with TFS work. I saw a presentation form Microsoft and the guy mentioned Maven and Ant Tasks. So I assume it can be done with a checkstyle plugin in Maven.
Is it possible to run CMD skripts?
The tool mentioned is probably the Team Foundation Server Build Extensions Power Tool December 2011.
These add the ability to trigger standard Java build scripts from Team Build.
The Java build processes just invoke maven or ant, so any task that checks code quality in these build tools should work just fine in Team Build. The team at Microsoft choose not to make a complex build template for the Java people, as they are well accustomed to their own build tools. So the build process templates to execute a Java build aver very thin by default. Everything is done through standard Java tooling. Team Build just invokes these and gathers the output.
As for executing command scripts and other executables as part of the build, there's a number of ways you can do this. The right way depends on the thing you want to accomplish.
If you want to execute something as part of the building of the binaries, you can use the msbuild exec task or an equivalent task in ant/maven.
If you want to execute something after all binaries have been built (say to trigger deployment) you can use a Build Activity in the build process template to execute a process
if you want to execute something before building the binaries on a build agent, you can use the same activity, but you should place it in a different place in the workflow.
The Visual Studio lab management build template and the Build Deploy Test build template serve as a good starting point to learn more about the possibilities of invoking processes during the build process.
As mentioned in other answers, the SVNBridge and possibly Git2tfs might provide alternative ways for the Java team members to access sources in TFS. They can then use the existing ant/maven tasks to get the sources and build the code.
You are very likely to get a lot of personal opinions on the use of TFS and whether or not it is a good fit, especially for JAVA development. That said, for the purposes of plugging in ANT/Maven/Jenkins you could install SVNBridge to give you the same functionality as you'd find with SVN.
It doesn't mean that there aren't plugins for TFS to support the tools, I've just found SVN related plugins are a lot more accessible.
I am wondering how I can quickly deploy the java dynamic web project that I built using eclipse on my mac to my Linode linux server? I already have a wordpress website running on the server and have also downloaded tomcat V6 and eclipse. Would I be able to manually copy the source, build and WebContent file contents? I would like to learn best practices for application deployment in the future but this project is very simple and I would like to be able to make it live as soon as possible. If you could also recommend any step by step tutorials I would really appreciate it.
thanks so much

You should consider to build a WAR. Eclipse is just an IDE, it helps to develop, not to deploy.
Build your war (you can use maven/ant/build it from eclipse) - whatever you chose.
Once its ready your "deployment task" becomes a matter of moving a single file from MAC to linux server.
Use Cargo. See how easily it can be integrated with Maven build. Here is an excellent blog post.
I started a new job recently. I've been a Java & XML web developer for two years. The new place I'm at has several large web applications, but none of them deploy to my local JBOSS server because some genius decided to create a Java Project instead of a Dynamic Web Project. I tried following the steps to convert the project but that creates a bunch of errors which I cannot resolve.
The people I work with are all consultants and never give me a straight answer on how I can develop/test my changes locally.
Has anyone had to program in a similar situation? If so... got any advice?
I've worked on projects like that, but with Tomcat as the server instead of JBoss. I develop in Eclipse using a normal Java project, and I follow these steps:
Run an Ant script to build the project into a new WAR in a temp workspace directory.
Use an Eclipse plugin to stop the local test server.
Run an Ant script to copy the WAR to the proper directory for Tomcat to pick it up and deploy it.
Use an Eclipse plugin to start the local test server.
Tomcat's fast and the project isn't huge, so this whole process takes 12-15 seconds. With JBoss being a full enterprise app server, I'd think it might take more time.
