Subject how to install and distribute master services in 4 nodes.
Date Sun, 06 Apr 2014 03:26:12 GMT
Trying to install hadoop by horton, there some many master services, such as HDFS, Yarn+mapreduce,
Nagios, Ganglia, Hive, Hbase and Pig as the image below.

Currently, only have 4 nodes, and as below, 3 nodes may ocuppy by master services, and only
1 node left for datanode.

Does all the master services neccessary.  After searching, seem all neccessary. Can all the
master services put into one node, if they are not cost much resources. Or even master services
are distrbuted for 3 nodes, I still can distribute data services into 3 or 4 nodes.
 
Any suggestion, thanks.
