[SOLVED] Ganglia fails to communicate with Apache HBase

Ganglia fails to communicate with Apache HBase

I installed Ganglia to monitor the HBase cluster. I'm using ganglia-3.3.0.

My Hadoop cluster comprises of 1 master node and 2 slave nodes.

Ganglia gmetad_server is configured on the master node

I changed the hbase/conf/hadoop-metrics.properties file.

hbase.class=org.apache.hadoop.metrics.ganglia.GangliaContext31
hbase.period=10  
hbase.servers=hostname_of_ganglia_server:8649

I started the service gmond on the master as well as slaves.

I get the basic metrics from the cluster (cpu, disk, load, ...)

But I'm not getting any HBase metrics from the Cluster.

Solution

The mistake was with the gmond.conf file. When I commented the following values, I got the HBase metrics in Ganglia.

mcast_join = 239.2.11.71
bind = 239.2.11.71
