Re: Hadoop Cluster
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

Hi,

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?

Thanks,
Savitha
