All nodes in no-hearbeat status

  • #44373

    I used ambari to deploy a hdp2.0 cluster which has 5 nodes. Hostnames are “host1,host2, host3, host4, host5″。

    The Hosts page shows that the 5 nodes are all in no-heartbeat status。But all service are running and the metrics are all OK。
    The ntp is ok.
    I used the api to get some information:

    curl http://node1:8080/api/v1/clusters/Test/hosts/
    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/”,
    “items” : [
    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/node1”,
    “Hosts” : {
    “cluster_name” : “Test”,
    “host_name” : “node1”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/node2”,
    “Hosts” : {
    “cluster_name” : “Test”,
    “host_name” : “node2”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/node3”,
    “Hosts” : {
    “cluster_name” : “Test”,
    “host_name” : “node3”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/node4”,
    “Hosts” : {
    “cluster_name” : “Test”,
    “host_name” : “node4”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/node5”,
    “Hosts” : {
    “cluster_name” : “Test”,
    “host_name” : “node5”
    }
    }
    ]
    }

    curl http://node1:8080/api/v1/hosts/

    {
    “href” : “http://node1:8080/api/v1/hosts/”,
    “items” : [
    {
    “href” : “http://node1:8080/api/v1/hosts/node1”,
    “Hosts” : {
    “host_name” : “node1”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/hosts/node2”,
    “Hosts” : {
    “host_name” : “node2”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/hosts/node3”,
    “Hosts” : {
    “host_name” : “node3”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/hosts/node4”,
    “Hosts” : {
    “host_name” : “node4”
    }
    },
    {
    “href” : “http://node1:8080/api/v1/hosts/node5”,
    “Hosts” : {
    “host_name” : “node5”
    }
    }
    ]
    }

    curl http://node1:8080/api/v1/clusters/Test/hosts/node1?fields=Hosts/host_state

    {
    “href” : “http://node1:8080/api/v1/clusters/Test/hosts/node1?fields=Hosts/host_state”,
    “Hosts” : {
    “cluster_name” : “Test”,
    “host_name” : “node1”,
    “host_state” : “HEALTHY”
    }
    }

    Hi Liao,

    Log in to each machine in your cluster separately

    On the Ambari Server host machine: ambari-server start
    On each host in your cluster: ambari-agent start

    and see if this helps.
