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

The most significant difference between the two, as per my view, is that HA eliminates the problem of 'NN as the single point of failure'. For a detailed info I would suggest you to visit the official web site. You might also find this link<http://blog.cloudera.com/blog/2011/02/hadoop-availability/> useful which talk about HA in great detail.

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.

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.
