I have successfully installed HDP on VM with CentOS 6.4 (64 bit) as OS, after successfully configuring the cluster via Ambari portal all services were started (showing green dot). (Note: both host and cluster are on same VM)
On Dashboard tab/page “Cluster Metrics” were blank with message “No Data There was no data available. Possible reasons include inaccessible Ganglia Service“. Clicked on services tab to check “Ganglia” service, service was started with below messages
Ganglia Collector [gmond] process down alert for HBase Master
Ganglia Collector [gmond] process down alert for slaves
Ganglia Collector [gmond] process down alert for NameNode
Ganglia Collector [gmond] process down alert for JobTracker
Checked Gangila service using following commands:
“service gmetad status” the result was “gmetad (pid 6133) is running…”
“service hdp- gmetad status” the result was =======================================
Checking status of hdp-gmetad…
“service gmond status “ the result was “gmond stopped”
“service hdp- gmond status” the result was “Failed to find running /usr/sbin/gmond for cluster HDPSlaves”
Clicked on “Host” tab and “Ganglia Monitor / Ganglia” was not started (red dot) tired to start by clicking on Action Start but I was not successful
The issue seems to Ganglia Monitor (gmond) not able to start on cluster HDPSlaves.
Can you please advise what could be the cause for this issue and how to trouble to shoot this ?
