> 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.
