yarn-resource-manager having nodes in unhealthy

  • #28189

    Software: HDP 2.0
    OS: CentOS 6.4
    Cluster size : 1-NN,RM, 1-SN, 5 data node – test cluster

    I am seeing all the nodes reported as unhealthy in the Application Manager Cluster. Due to this ,the jobs are not getting executed. I am able to upload the files successfully from hadoop fs command line.

    >>> Following the snippet of the yarn-yarn-resourcemanager-xxxx.log
    qatstvm16.sensage.com:45454 Node Transitioned from NEW to RUNNING
    2013-06-24 20:04:48,999 INFO capacity.CapacityScheduler (CapacityScheduler.java:addNode(710)) – Added node qatstvm16.sensage.com:45454 clusterResource:

    Any pointers to debug/fix this is much appreciated.

    Hi Satish,

    I am researching this, will get back to you when I have an answer.



    Do you see anything on the resourcemanager web-UI, specifically the nodes’ page? The node’s page should show you the reason why it became unhealthy. Do you have any node health script configured?


    was this resolved? The ticket seems to be open for long time.
    What was the resolution?
