Answer 1

1. your system should be installed with hadoop, make sure it is running.

2. you need to copy the "hadoop-eclipse-plugin-.jar" you may download it from google. into the "/eclipse/plugins" directory. After this you need to restart the eclipse.

3. In eclipse you need to configure hadoop configurations by giving respective port numbers and hostname

Answer 2

you need to copy the "hadoop-eclipse-plugin-.jar" from your "/hadoop-/contrib/eclipse-plugin directory" into the "/eclipse/plugins" directory. After this you need to restart the eclipse. But this doesn't work a few times. A possible reason could be the absence of a few jar files in the hadoop-eclipse-plugin-.jar. Try this an d let me know it work for you - Extract the hadoop-eclipse-plugin-.jar, and add the following 5 files into "hadoop-eclipse-plugin-0.20.203.0\lib - commons-configuration-1.6.jar, commons-httpclient-3.0.1.jar, commons-lang-2.4.jar, jackson-core-asl-1.0.1.jar, jackson-mapper-asl-1.0.1.jar. After this add the names of these jars into the "haoop-eclipse-plugin-*\META-INF\MANIFEST.MF" file. Your MANIFEST.MF file should look something like this -

After doing this re'jar' the package and replace the old "hadoop-eclipse-plugin-*.jar" in the /eclipse/plugins directory and restart the eclipse.
