    I am trying to configure a Hadoop cluster manually using the following guide


    I am using 5 SLES 11 VMs (1 master, 1 secondary, 1 HA and 2 data nodes, each on a separate VM)

    I am now stuck on Step 4 which is starting JobHistory Server. Once we start this and go to the UI for Yarn ResourceManager, we see the two data nodes as Unhealthy with this health report : ERROR check containerexecutor, OK: disks ok, ;

    The ResourceManager log give this message for both data nodes
    Node Transitioned from NEW to RUNNING
    Node Transitioned from RUNNING to UNHEALTHY

    I checked permissions on containerexcecutor and they are exactly the way they are supposed to be —Sr-s— root hadoop containerexecutor

    Any idea what else could be the source of this problem?
