I tried to add another host via cloudera manager .
I followed the below steps
1. Hosts - > Add hosts -> provided the ip address -> CM asked me to create a host template but i gave none and finised .
2. Found the host in good health .
3. Cluster -> HDFS -> Instances -> Add -> I added a Datanode with the new hosts.
(Now the Datanode i added was not starting , When i search for logs via UI i dont find any . I searched for logs in logs/datanode folder , but there was no Datanode folder in Var .)
4. Cluster -> Deploy client Configuration -> Completed -> Still the Datanode was not starting .
Please help .

Issue resolved . I added hosts by stopping the Datanodes agent first and then proceeded . After adding the hosts i started the agent . It worked :).

Data directory is local filesystem storage location for each datanode in your cluster. Search for "dfs.datanode.data.dir" property in hdfs-site.xml file to find out. You can also search in cloudera configuration search tab of your datanode.
