    Default Kettle - Hadoop connectivity - unable to connect to HDFS server


    I have just installed Kettle and I'm attempting connectivity from Spoon to a remote Hadoop cluster. I referred to a similar thread.

    Below are the versions of the different tools involved :

    hadoop version
    Hadoop 2.3.0-cdh5.0.1
    Subversion git:// -r 8e266e052e423af592871e2dfe09d54c03f6a0e8
    Compiled by jenkins on 2014-05-06T19:01Z
    Compiled with protoc 2.5.0
    From source with checksum 6ce1c599ee996a0a6505d2579e62ffa
    This command was run using /usr/lib/hadoop/hadoop-common-2.3.0-cdh5.0.1.jar
    Kettle/Spoon : 5.1.0

     cat /etc/hadoop/conf.cloudera.hdfs/core-site.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <!--Autogenerated by Cloudera Manager-->
    As mentioned in the documentation , in all the relevant, I added the following entry


    When I attempt to edit a 'Hadoop Copy Files' job, I get an 'unable to connect to HDFS' as shown in the image below :

    Can anyone provide me inputs as to where am I going wrong ?

    There are some other *-site.xml files in the cdh50 folder (such as yarn-site.xml) that likely contain hostname references to the Cloudera QuickStart VM (cdh5.clouderamanager.test, e.g.), if you update the hostnames/ports to point at your cluster does it work?

    Also, are you using YARN on your CDH 5.0.1 cluster, or MapReduce 1? If the latter, you have to change in the cdh50 folder to use configuration "mr1" instead of the default "mr2".

    Lastly, if you are trying to connect to a secure cluster, you'll need PDI Enterprise Edition and to follow the setup instructions located at the InfoCenter (

    I am having a similar issue with CDH5 and Hadoop 2.5. Did you figure this out?
