    I installed HDP 1.3.2 with ambari on VM instance.
    I have 2 problems.
    1 – Every services are normally operated except for the MapReduce service.
    It alerts that “JobTracker CPU utilization – Unable to contact host: ”
    2 – CPU % of HDFS master node very high and other nodes are normal. cpu wio hits over 1000 %.
    but, In Ganglia monitor, cpu wio is normal under 10%.

    Since I had to install HDP on the VM environment, all the ports used in services were opened manually.
    I thought that the problem is some ports weren’t opened. so, I tried to open all the ports used in services.
    But I didn’t solve the problem.

    How can I solve this problem?
    Please help me someone who knows.
