edit : I am using windows 7 so firstly install cygwin than hadoop1.0.4 and started service on
http://127.0.0.1:50030/ and http://localhost:50070/ successfully.
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/

Url to download the Sikulix setup 1.1.3 jar : https://launchpad.net/sikuli/+download
Command used to install Sikulix setup 1.1.3 jar -->java -jar Sikulix setup 1.1.3 jar
While installing sikulix setup 1.1.3 jar, i am getting the error as 'Something serious happened! Sikuli Not Usable'... Check the error log
First of all there is new version 2.x of Sikuli that works on latest Linux OS. Old 1.1.3 is not supported anymore
However the answer your question: you need manually to install Java opencv library in older Sikuli versions. Note this will work on Ubuntu 16 and 14.
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 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 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
