Hi Savitha

HA is a new feature n hadoop introduced in Hadoop 2.x releases. So It is a new feature on
top of Hadoop cluster.

Ganglia is one of the widely used tools to monitor the cluster in detail. On a basic hdfs
and mapreduce level, the JobTracker and NameNode web UI would give you a good consolidation
on hadoop cluster.

Subject: Hadoop Cluster


I am trying to understand the difference between HA cluster and Hadoop cluster. Can this group
help me understand, how differently Hadoop cluster should be monitored?
