[jira] [Created] (AMBARI-4555) Nagios alert for NN process fails if
Port is changed
Andrew Onischuk created AMBARI-4555:
---------------------------------------
Summary: Nagios alert for NN process fails if Port is changed
Key: AMBARI-4555
URL: https://issues.apache.org/jira/browse/AMBARI-4555
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 1.5.0
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.
