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'm planning to build a web crawler using nutch and solr. I want to know which version of hadoop should I install to work with nutch 1.15.
Nutch 1.15 is built with Hadoop 2.2.0 but it runs also on Hadoop installations using higher versions of Hadoop 2.x and 3.x.
I have upgraded my AndroidStudio today to latest stable version 2.3 (with gradle plugin 2.3.0 and gradle 3.3): now, I am not able to build my project which ran fine under AndroidStudio 2.2.3.
When I try, I am stuck at :app:transformJackWithJackForDebug as long as I don't kill my java platform process.
It is the same problem than this post I guess but on stable release.
Any help will be greatly appreciated :)
I killed many hours for the same issues after that i got link and its working fine at my end.
To use "Retrolambda" add few dependency.
dependency to your build.gradle file.
classpath 'me.tatarka:gradle-retrolambda:3.2.0'
Added dependency into app/build.gradle file.
apply plugin: 'me.tatarka.retrolambda'
Please clean your build and run. it will work fine.

all the best.
With Android Studio 3.0 (plugin 3.0) they are recommending to disable the Jack compiler as its been deprecated.
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

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/
