Hello All,

For some strange reason i can't get the MapReduce Service to start during
the installation is stucks on te Starting MapReduce Service.

the error i get is: Command completed with 0/1 successful subcommands

Details:

    Hi Paul,

    The message that you shared indicates that CM got to the point of actually
    running the hadoop command to start the tasktracker:
    + exec /usr/lib/hadoop-0.20-mapreduce/bin/hadoop --config
    /run/cloudera-scm-agent/process/31-mapreduce-TASKTRACKER tasktracker

    Therefore, more information should be present under the MapReduce service
    logs. Please navigate via Cloudera Manager to the MapReduce Service, and
    grab the latest information from the log (should be in a window pane at the
    bottom of the UI)
    Please send that information so we can help to diagnose

    Thanks,
    Adam

    Hello Adam Thanks for your reaction but it fails on installing and the log
    file is (looks like) empty
