I have installed hadoop 2.4.1 which is working and i am trying to configure eclipse for hadoop. I dont see an eclipse plugin for hadoop 2.4.1 version. Does anyone know where to pick that plugin and use it eclipse.
I understand that most hadoop distributions would have eclipse plugin in it, but unfortunately 2.4.1 doesnt have that as far as i see.
Where could we get the eclipse plugin and what is the eclipse-plugin version for that
an additional question on this, i am seeing some .a files in hadoop/lib folder. what are those and how to open those, because i suspect it might have library jar files.
There is no official eclipse plugin from hadoop project.
https://issues.apache.org/jira/browse/YARN-1487
But it can be compiled as per the below tutorial
https://github.com/winghc/hadoop2x-eclipse-plugin
Also, check out Hadoop development tools (HDT) for official hadoop eclipse plugin support.

I want to build hadoop eclipse plugin for hadoop 2.7.1 version. So how to build this plugin?
AFAIK the hadoop eclipse plugin is very very old and unmaintained. Some time ago I tried to use it with hadoop 2.3 and even I was able to install it, it never worked. I don't recommend you waste your time with old plugins.
I am using Eclipse Helios and want to migrate to Indigo.
I have installed Indigo and m2e and subclipse plugin. I was able to import maven project as well as projects from svn.
But from the next day, Svn is missing from perspective and while trying to import maven projects, I am not able to find maven in the list.
I have uninstalled and installed again but same issue occured again.
Is it because both Helios and Indigo installed in my machine ?
Please help me solve this problem.

That shouldnt create any issue at all. I have multiple versions of eclipse installed in my system and they all seem to work fine.
As far as the m2e and subclipse plugin is concenred, I have used it personally on Indigo without any issue at all and there doesn't seem to be any incompatibility issue.
It maybe possible that eclipse plugins have gotten a bit messy and need a re-start. Goto the directory where you have installed eclipse and add this line on the top of the eclipse.ini file.
-clean
-startup
....the rest of the settings and params
Then start your eclipse, it will attempt to clean and re-load each plugin again.
I want to run a Hadoop MapReduce program (for example WordCount) with NetBeans. I found that there is "KarmaSphere studio for Hadoop" that is a plugin in NetBeans.
I followed the instructions given in the link below, to install the plugin : http://www.hadoopstudio.org/home/installation-guide/
But, when I add the plugin name and URL, the "KarmaSphere Studio" does not appear in my available plugins. So I can not download and install it.
I have NetBeans 7.3.1 with JDK7.
Anybody knows what should I do?
It seems netbeans is not supported by karmasphere studio for hadoop.For programming Hadoop in Eclipse, see here http://arifn.web.id/blog/2012/05/15/programming-hadoop-in-eclipse.html

Check if you install hadoop properly. Try to install hadoop plugin, as you can see in install plugin. You can see a tutorial for this in haddop video tutorial. Also, take a look to eclipse setup for hadoop development.
Eclipse Indigo is version 3.7. You can read "Any eclipse before 3.6 is compatible to the eclipse plugin. (Doesn't work with Eclipse 3.7)" http://www.orzota.com/eclipse-setup-for-hadoop-development/
I have a properly set up Maven project, and my Netbeans on Windows recognizes it and can build it properly, but my Netbeans on Ubuntu wouldn't even see the project as a Netbeans project.
Any idea how to fix this?
Maven support in Netbeans comes in the form of an official plugin. The version that ships with Ubuntu has almost no plugins installed. To resolve this, navigate to Tools ▶ Plugins and install the Maven plugin from there. After a restart of the IDE, all Maven projects should be recognized automatically.
If you don't see the list of plugins, make sure the repositories are enabled in the Tools ▶ Plugins ▶ Settings tab. Check at least 🗹 Certified Plugins and 🗹 NetBeans Distribution. Reload the catalog in the Available Plugins tab. Now you should see a list of all available plugins.
I had the same issue on my Xubuntu when I downloaded netbeans with synaptic.
I have uninstalled the netbeans on synaptic et install the netbeans with all avalaible on netbeans website and it works fine (last column). I can now import maven project. Hope it helps you.
