> Hi,
> The nagios alert for Namenode process reports error , if NN port is changed from default 8020 to example 54310.
> more /etc/nagios/objects/hadoop-services.cfg
> define service {
>         host_name               linuxhdp
>         use                     hadoop-service
>         service_description     NAMENODE::NameNode process on linuxhdp
>         servicegroups           HDFS
>         check_command           check_tcp!8020!-w 1 -c 1
>         normal_check_interval   0.5
>         retry_check_interval    0.25
>         max_check_attempts      3
> }
> It should either be configurable or should take the value from core-site.xml based on value of below param.
>  <property>
>     <name>fs.defaultFS</name>
>     <value>hdfs://linuxhdp:54310</value>
>   </property>
> If we change /etc/nagios/objects/hadoop-services.cfg it is getting overwritten by Ambari.
