Description

1) Configure NN HA
2) stack 2.0.6 (but check stack 2.1 as well)
3) Two alerts show" check_tcp: Port must be a positive integer"

NameNode process on c6401.ambari.apache.org
NameNode process on c6402.ambari.apache.org

4) Looked at /etc/nagios/objects/hadoop-services.cfg
5) Saw:

define service {
        host_name               c6401.ambari.apache.org
        use                     hadoop-service
        service_description     NAMENODE::NameNode process on c6401.ambari.apache.org
        servicegroups           HDFS
        check_command           check_tcp_wrapper!//test!-w 1 -c 1
        normal_check_interval   0.5
        retry_check_interval    0.25
        max_check_attempts      3
}
define service {
        host_name               c6402.ambari.apache.org
        use                     hadoop-service
        service_description     NAMENODE::NameNode process on c6402.ambari.apache.org
        servicegroups           HDFS
        check_command           check_tcp_wrapper!//test!-w 1 -c 1
        normal_check_interval   0.5
        retry_check_interval    0.25
        max_check_attempts      3
}

Notice in the above //test is the name of my nameservice.

Attaching screen shot of my config. So looks like it's grabbing port from the wrong prop.
