    I am trying to setup Eclipse Indigo to run Map/Reduce prgs using “hadoop-0.20.3-dev-eclipse-plugin” and “hadoop-0.18.3-eclipse-plugin”

    Copied hadoop plug to eclipse/plugins.
    Open Eclipse in MapReduce perspective.
    Add MapReduce Locations
    Entries
    Map/Reduce Master
    Host : 192.168.15.128
    Port : 8021
    DFS Master
    Host : 192.168.15.128
    Port : 8020
    User : root

    first parameter changed to root for property
    hadoop.job.ugi: root,xxxxxx
    mapred.system.dir: /hadoop/mapred/system

    followed

    http://developer.yahoo.com/hadoop/tutorial/module3.html

    But unable to connect.
    Got an error unknown host:http

    And also tried with ports 9001 and 9000 instedad of 8021 and 8020, but same error.

    And I tried with one more plugin from sandbox,
    Pulled the Eclipse plugin from sandbox /usr/lib/hadoop/contrib/eclipse-plugin/ folder -> to Eclipse/plugins.
    but nothing changed.

    Please can anyone suggest me any other properties to be changed or any modifications in hadoop/conf/hadoop-site.xml.

    Hi,

    I’ve managed to make this work, but using hadoop-0.18 from yahoo site and the provided plug-in bundled in the tar file. I think your plug-in version will not be able to connect to that version of Hadoop. I’d recommend building your own version of the plug-in, you can find how to do it here:

    I’ve tested this with Hadoop 2.0 and seems to work…

    Hope that helps
